I doubt that 2020 DEX will be able to beat CEX, because based on the data I saw on the coinmarketcap site.
CEX still has a higher volume than DEX, also the number of coins listed on CEX is still more. So CEX is still more
popular and is still widely used by traders, DEX still has a long way to go in order to beat CEX.
But the presence of Uniswap makes a few changes, the way it works is the same as forkdelta so there is an increase in volume for dex, although cex is still far ahead for now, hopefully the dex platform will appear more next time.
