I think btc failed everyday so no more good decided now for buy and hold. At least we should wait for the next market situation when gonna stable somethink like btc price. Anyway if btc price will brackdown under $15k then we should ready for buy next ath. Even in my opinion Don't take risk invest in others currency.
Opportunity comes only when people are scared and leave. I don't think bitcoin has failed, now is not a good time to buy. When is the time you think it's time to buy?.
Many people bought when bitcoin dropped to $ 30,000 and they thought it was the bottom but now we have a chance to buy at $ 20,000, a much higher discount.
We cannot predict where will be the final bottom for bitcoin but in my opinion, bitcoin has very little chance of falling below $ 15,000, which is almost not going to happen. So the current price is suitable to buy.
