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....
decentralized exchanges are sure to be the next big thing. But the networks need to scale to support the volume unfortunately.
Also, those cross chain exchanges need to be a thing too so you're not stuck only with ETH and ERC20 tokens.
