A few years ago, you didn't need to play DEX to make good profits with CEX. But in the past year, not playing DEX has been a big mistake, especially if your profit goal is over x2.
The perception: "Cex is safe - Dex is risky" is outdated.
The truth should be: "Cex is no longer safe - Dex is no longer too risky."
Just try to reflect on it, how many times have you traded CEX in the past year?
