I agree with Flux0z, adoption takes time. Conditions are different Slash61, but DEX will have to wait many
more years, beacause attention is on CEX. New people hardly understand crypto-currencies, we can't bother
them with CEX and DEX, they heard for Binance, for other big crypto-exchanges, how traders make money
there, and they will need time to learn about DEX.
Time for DEX is coming, one day CEX will be behind DEX, but maybe for +10 years, if not a lot longer.
the development will indeed require a long time. we cannot measure that time for sure but in the current achievements, DEX is good enough to have a large trader. but as you said, a great time for DEX will occur in the future.
As soon as people realize they can make tons of money from running nodes on DEX's such as Blocknet. Good passive money, then I'm sure as volume picks up that we'll see a snowball effect on the use cases of DEX's.
