People aren't learning before investing, this is why they will loss in the long run. Just like many people are more prefer to choose Centralized exchanges rather than Decentralized exchanges. I know the problem is about the liquidity, I mean if many people are joining more into DEX the liquidity will goes up and no lack of liquidity.

Since the fees on Ethereum network is ridiculous, many investors with low budget can't buy Ethereum or they only loss with the fees. That's why they migrate to another coin with cheap fees.

If Ethereum 2.0 already launched, the fees will be cheaper and there's another story will be make by Ethereum.
