Here's a simple solution for cryptocurrency woes: use what you buy.

When stuff is just there to be there it doesn't have a value outside of people hoping to sell it. This means nobody but investors will buy it, so as soon as the coin isn't shiny and new anymore it's worthless. When stuff does have a use, people will want to buy it. This causes the market to grow.

Only buy coins you yourself actually use for things that aren't investing. "Normal people" uses are best. Things like, say, paying for your web hosting: not gambling or anything involving TOR!

If enough people use cryptocurrency as an actual currency then the market naturally will improve. Be the change you want to see.
