NANO is possibly the best coin for transactions, it has near instant transactions with no fees. It does this by having 'blocks' that are only one transaction in size, and having the user 'mine' his own block preemptively, so that when you make a transaction all the computation is already done. It is only if you wish to send multiple transactions in quick succession that there will be any delay, which will then be based on your own computers processing speeds. At least that is as far as I understand it. They call it a 'block lattice' rather than a blockchain.

@lagster15 Yes Nano has some very interesting features that separate it from other coins including : Instant transactions, No fees, and is Infinitely scalable. if your looking for more information about nano I made a post about it earlier with more information https://steemit.com/cryptocurrency/@popswc/nano-the-future-of-crypto-currency

Honestly there are so many coins that all do the same thing; the main thing moving prices is speculative investment at this point (My humble opinion).
