Almost everyone would be having this regret of not buying bitcoin at the dip  last year or not buying it at all, those who bought a few will be also sad that couldn't buy more because they never expected the price to go this high, life is full of alot of regrets, but what can we do since we can't predict or know how the future will look like for a particular coin, so don't bother yourself too much about it, and as for eth and their high gas fees it's  really bad that small investors can no longer move their ERC20 tokens or trade on DEX anymore since they can't afford the high gas fees, I just hope this will be corrected real soon.
