Meanwhile... Due to the high rate of transactions fees, I can perceive it that lot of short term Investors would tend to have their assets stored in a Centralized blockchain for easy transactions
Investors don't mind too much about transaction fee. Let me tell you why?
They don't usually move their assets so they don't care too much about fee of transaction. Who do care most about transaction fee?
Traders on DEX, gamblers and gamers with NFTs, GameFi, Metaverse and similar.
A person can move between chains but to store their assets, they will choose best ones, like Bitcoin, Ethereum, not shit coins. Save $20 in transaction fee and lose $1000 or bigger, it's not smart.
