Treasury coins
Dash is the most famous coin with a treasury. Steem can also crowd fund in a way. Who are the other treasury coins?
Cardano - the new coin from Charles Hoskinson will have atreasury when it moves to proof of stake
PIVX the dash clone has a treasury
Decred has atreasury
who else?
I think this is a powerful tool that will get more attention in 2018 as icos (money up front ) die down and dash projects are completed.
