A lot of coins are focusing on exchanges, smart contracts etc. Then there are many very small coins for specific uses or ones like Digibyte that sounded good but never got any traction.

I wasn't around, but I don't imagine that in the past people carried around 20 dollar gold pieces, they probably just used silver. So if we think of Bitcoin as a new type of digital gold, what will be the silver to actually buy things? Could a deflationary crypto ever work? Meaning any crypto that has a limited amound and doesn't inflate a bit each year. People need to be incentivized to actually spend it rather than hodl and hope it goes up.

Anyway, I'm hoping to get educated here. The candidates I currently see are Bitcoincash, Litecoin, and Dash. I choose these because they are all well known, seem to have pretty good teams, and are used in some parts of the world at least alongside bitcoin.

Which one do you think will still be here in 10 years? Any potential cryptocurrency coin I missed?
