What about decentralised exchanges... I think I saw a post on that..
Also because of scalability issues, coins like IOTA, Raiblocks, hashgraph and xtrabytes seems to offer some form of alternative tech that is not a direct "block-chain" implementation.
Any time a potential coin comes about, the prices will surge and decline like waves of the ocean in a storm...... eventually there will only be a few coins left....(with many child tokens)

XRP is crippled decentralisation....
