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.
