Do you think that 2018. is the year of altcoins? Personally, I think that, for example, LTC is showing us just a sneek peak of its full potential.
The sonner people get accustomed to cryptocurrencies and blockchains, the sooner the focus will shift from the price of the particular cryptocurrency to the actual benefits we get from them.

There are a lot of useful cryptocurrencies, if BTC stabilizes a bit, I can see other cryptos gaining massive media coverage.
