I think we need to control our emotions when investment is involved, don't sell when you are in panic. Try to think carefully and think more than 7 times before you click or do a transaction. ETF delay is not a bad news for me. I think it is a way for people to do panic selling and those rich people will abuse the dip and buy all the cheap BTC and after that, the ETF will be approved.
Right now, the market is green again and I think many people regrets selling their coins at a low price.
This is just my opinion, how about yours?
You should always do an independent analysis before deciding what to do. This year, the lowest price for Bitcoin was $ 5,800, so why sell when it costs near the bottom? This is the same thing that you decide to buy when the price reaches $ 20,000. Certainly, the situation now has more to do with purchases.
