I always thought it is really annoying to have so many defferent walkets and the fact you have to move the currencies around a lot.
Maybe something similar might come with another hard fork?

"So shooting for a decentralised exchange directly first might not be the best idea. I think the ability for anyone to deposit and power up their cryptocurrencies on the Steem blockchain may present a better case before any form of decentralised exchange becomes successful."
Completly agree on that!

Great ideas overall I like them!
Cheers
