Secara sederhana, mata uang kripto atau Cryptocurrency bisa dibilang adalah mata uang atau aset yang bentuk dan pengelolaannya secara digital.

Mata uang yang biasa dipakai untuk transaksi virtual ini muncul sebagai gerakan desentralisasi, agar pergerakan aset tidak bergantung pada pihak ketiga seperti bank dan pemerintah.

Artinya, transaksi yang dilakukan dengan mata uang kripto tidak membutuhkan perantara. Pembayaran berlangsung secara peer – to – peer, langsung antara pengirim dan penerima. Transaksi dicatat dan berjalan di atas sistem yang disebut Blockchain.

Layaknya mata uang di dunia nyata, yang banyak macamnya, seperti Rupiah, Dollar, Dinar dan lainnya, mata uang virtual pun memiliki banyak wajah. Sebut saja Bitcoin, Ehtereum, Litecoin,Steem, Ripple, Stellar, Dogecoin, Cardano, Eos, Tron dan ribuan lainnya.

Tercatat di Coinmarketcap, terdapat 9.826 jenis mata uang kripto yang sekarang beredar di seluruh dunia.

Cara Penggunaan Mata Uang Kripto

Selanjutnya, apa saja yang bisa dilakukan dengan menggunakan mata uang digital? Berikut di antara cara memakai mata uang yang pertama kali ditemukan Satoshi Nakamoto ini.

1. Melakukan Investasi

Prinsip dasar ekonomi, supply and demand juga berlaku di cryptocurrency. Di mana harga akan naik ketika permintaan banyak dan ketersediaan terbatas. Semakin banyak yang melakukan investasi aset kripto, maka nilanya akan bertumbuh.

Namun berdasarkan grafik yang disajikan di tradingview, market Cryptocurrency tampak terus bertumbuh. Sehingga investasi kripto sejauh ini menampakkan potensi yang positif.

Namun tetap jangan terburu-buru memutuskan berinvestasi di Cryptocurrency dengan pengetahuan yang terbatas. Karena investasi aset kripto masih tergolong kategori high risk (resiko tinggi).

2. Membeli Barang atau Jasa

Semakin ke sini banyak perusahaan atau organisasi yang telah menerima pembayaran dengan mata uang virtual. Berbagai jenis transaksi seperti perhotelan, restoran, penerbangan, hingga aplikasi bisa dibayar dengan menggunakan mata uang kripto.

Setidaknya, dua perusahaan yaitu Overstock dan Newegg telah menerima berbagai jenis mata uang kripto sebagai alat pembayaran. Namun, sebagian besar lainnya baru menerima bitcoin saja.

3. Mining (Penambangan)

Penambangan merupakan salah satu cara menambah jumlah mata uang kripto. Prosesnya dilakukan dengan memecahkan perhitungan matematika yang rumit untuk menambah block ke sistem bockchain.

Perlu komputer dengan spesifikasi khusus dan tentunya keahlian yang tidak sembarangan untuk dapat menjadi seorang miner atau penambang. Oleh sebab itu, muncul jasa-jasa dan perusahaan yang membantu urusan ini, mereka pun dibayar dengan komisi dari transaksi mata uang kripto.

Bagaimana Cara Kerja Cryptocurrency

Seperti yang dijelaskan di atas, perbedaan Cryptocurrency dengan sistem keuangan konvensional adalah mata uang virtual ini sifatnya desentralisasi. Sedangkan model transaksi yang selama ini kita kenal bersifat tersentralisasi.

Contoh sederhana untuk menjelaskan sifat tersentralisasi yang berlaku pada model konvensional adalah ketika orang tua ingin mengirim uang bulanan ke anaknya di perantauan.

Beliau menggunakan layanan perbankan seperti ATM, Mobile Banking, atau datang langsung ke bank. Lalu, si orang tua tadi akan mentransfer uang yang ingin dia kirim ke nomor rekening anaknya. Transaksi ini menggunakan pihak ketiga yaitu bank sebagai perantara.

Proses yang terjadi sebenarnya adalah uang yang ditransfer masuk dulu ke bank, baru diteruskan ke penerima oleh pihak bank. Karena dilakukan secara real time, perpindahan tersebut tidak terasa.

Namun yang akan terasa akibat proses melalui perantara ini adalah si orang tua harus mengikuti kebijakan pihak bank. Seperti imbalan yang harus dibayarkan, berupa biaya administrasi, baik yang dikeluarkan saat transaksi dilakukan atau dalam bentuk potongan bulanan.

Sedangkan pada Cryptocurrency yang terdesentralisasi, tidak ada pihak yang berperan sebagai perantara. Transaksi langsung dilakukan antara pengirim ke penerima.

Setiap komputer yang berada di jaringan tersebut (di seluruh dunia) mencatat transaksi yang terjadi. Komputer-komputer tersebut dioperasikan oleh para miner atau penambang yang ikut mencatat dan mengawasi transaksi di jaringan.

Para penambang tersebut akan mendapatkan komisi dengan uang kripto yang digunakan. Namun seperti dijelaskan di atas, tidak semua orang bisa menjadi miner. Pemrosesan komputasi yang rumit untuk mengurai kriptografi yang digunakan membutuhkan keahlian khusus dan device yang memadai.

Sifat desentralisasi ini yang menjadi ide pokok dari sistem Blockchain. Teknologi Blockchain sendiri adalah platform yang digunakan dalam transaksi menggunakan mata uang digital Cryptocurrency.

Cryptocurrency di Indonesia

Dilansir dari CNBC , Indonesia sudah mengeluarkan izin untuk 299 Cryptocurrency, di antaranya Bitcoin, Ethereum, Xrp/ripple, Tether, Bitcoin cash, Binance coin, USD Coin dan lainnya. Walaupun mengalami penurunan, Bitcoin masih menjadi yang paling populer.

Namun, Undang-Undang No. 7, Pasal 1 Ayat 1, tahun 2011 masih menyatakan bahwa alat pembayaran yang diakui di Indonesia hanyalah mata uang Rupiah. Artinya, mata uang kripto belum bisa dipakai untuk alat transaksi di tanah air.

Meski demikan, keberadaan Cryptocurrency tidak ilegal. Kamu diperbolehkan untuk menyimpan atau memperjualbelikannya sebagai aset. Peraturan No. 5 Tahun 2019 menjadi landasan hukum untuk penyelenggaraan pasar fisik aset kripto di Indonesia.

Bank Indonesia (BI) dikabarkan berencana menerbitkan mata uang rupiah digital. Mata uang tersebut nantinya akan dikelola bank sentral. Guna melancarkan niat mereka, BI berusaha membangun kerja sama dengan bank sentral lain di berbagai dunia.

What is Cryptocurrency?

This currency commonly used for virtual transactions emerged as a decentralized movement so that the direction of assets did not depend on third parties such as banks and governments.

That is, transactions made with cryptocurrencies do not require intermediaries. Payment takes place peer-to-peer, directly between the sender and the recipient. Transactions are recorded and run on a system called Blockchain.

Like real-world currencies, many kinds, such as Rupiah, Dollar, Dinar, and others, virtual currencies also have many faces. Call it Bitcoin, Ehtereum, Litecoin, Steem,Ripple, Stellar, Dogecoin, Cardano, Eos, Tron, and thousands more.

Recorded in Coinmarketcap, there are 9,826 types of cryptocurrencies currently in circulation worldwide.

How to Use Cryptocurrencies

Furthermore, what can be done using cryptocurrencies? Here's how to use this currency that Satoshi Nakamoto first discovered.

1. Making Investments
The basic principles of economics, supply and demand also apply in cryptocurrencies. Where prices will go up when demand is pled, and availability is limited. The more you invest in cryptoassets, the more they will grow.

But based on the charts presented on the tradingview, the Cryptocurrency market appears to continue to grow. So crypto investments have so far shown positive potential.

But still do not rush to decide to invest in Cryptocurrency with limited knowledge because crypto-asset investment is still classified as a high-risk category.

2. Buying Goods or Services

More and more here, many companies or organizations have received payments with virtual currency. Various types of transactions such as hospitality, restaurants, flights, and applications can be paid using cryptocurrencies.

At least two companies, Overstock, and Newegg have accepted various types of cryptocurrencies as means of payment. However, most of the others only buy bitcoin.

3. Mining
Mining is one way to increase the number of cryptocurrencies. The process is done by solving complex mathematical calculations to add blocks to the blockchain system.

Computer with particular specifications andexpertise is not careless to be able to become a miner. Therefore, the services and companies that help this business appear are also paid with commissions from cryptocurrency transactions.

How Cryptocurrency Works

As explained above, the difference between Cryptocurrency and conventional financial systems is that this virtual currency is decentralized. In contrast, the transaction model that we have known is centralized.

A simple example to explain the centralized nature of conventional models is when parents want to send monthly money to their children overseas.

He uses banking services such as ATM, Mobile Banking or comes directly to the bank. Then, the parent will transfer the money he wants to send to his son's account number. This transaction uses a third party that is a bank, as an intermediary.

The process that happens is money transferred first to the bank, then passed to the recipient by the bank. Because it is done in real-time, the transfer is not felt.

But what will be felt as a result of the process through this intermediary is that the parents must follow the bank's policy. Such as rewards to be paid, in the form of administrative fees, either incurred when the transaction is made or in the form of monthly deductions.

As for decentralized Cryptocurrencies, no party acts as an intermediary. Direct transactions are made between the sender to the recipient.

Every computer on that network (worldwide) records transactions that occurred. These computers are operated by miners who participate in recording and supervising transactions on the web.

The miners will earn commissions with the used crypto money. But as explained above, not everyone can be a miner. Complex computational processing to parse the cryptography used requires specialized skills and adequate devices.

This decentralized nature is the main idea of the Blockchain system. Blockchain technology itself is a platform used in transactions with cryptocurrency cryptocurrencies.

Cryptocurrency in the Indonesia

As reported from CNBC, Indonesia has issued permits for 299 Cryptocurrencies, including Bitcoin, Ethereum, Xrp/ripple, Tether, Bitcoin Cash, Binance coin, USD Coin, and others. But despite the decline, Bitcoin is still the most popular.

However, Indonesia's law only recognized means of payment is Rupiah. That is, cryptocurrencies can not be used for transaction tools in the country.

Although for the sake of it, the existence of Cryptocurrency is not illegal. You are allowed to store or trade them as assets. Regulation No. 5 of 2019 becomes the legal basis for implementing the physical market of crypto assets in Indonesia.

Bank Indonesia (BI) is reportedly planning to issue a digital rupiah currency. The central bank will then manage the money. To launch their intentions, BI seeks to build cooperation with other central banks around the world.
