Well, for now all we can do is hodl the fuck out of them.

I, personally, agree that Cryptocurrencies will gain both in weight and price sooner or later - again.
Not only is the market demand for these coins still high, but also is the idea behind a blockchain highly feasible.

Sadly, the fall in prices is mostly due to everyone selling everything they've got out of shock of never being able to access their crypto wallets again, I presume.

Pretty certain we might see 15000-20000$/BTC in late 2018 or early 2019. This will also affect other currencies, for whatever reason, and they're gonna rise in prices as well.

Which can be good for those who're hodling, but bad for those not "getting on it". :D
