Nowadays, no one believes BTC will dramatically drop to below $20K in 2021. Everybody is crazy in bull market , but risks are building up.
It is still possible to see bitcoin drop below $20k this year, but I do not want to expect that price after bitcoin price rise so far. But we still need to be careful because if the price drops to that price, we can buy more bitcoin at a low price and we need to use that chance to buy bitcoin. But I guess the price will continue to rise as the green candle and the bullish trend are still on the market. But I think that the flash dump can happen in the short term or long term because that moment can happen anytime.
