Its not bull market yet, be calm and expect the price to go down. Just because crypto pumped a little bit doesn't mean we are in bull market!!! I mean I wish we were in a bullrun, but we are not in one yet so please don't get your hopes too high because you will get 100% dissapointed soon.
Bitcoin pumped to 21k dollars and you all got hyped like its the second coming of Jesus, right now its 20840$ (data from coinmarketcap) and it might go even lower. Just hodl what you have and wait, don't spread unnecessary hype or FUD.
What caused this pump? I don't know, maybe its corelated with stocks or maybe that ugly bitcoin dress Miss El Salvador wore influenced some guys to buy, but that doesn't matter tbh. Our situation can change in a week maybe even in a day! I personally hope we will see even more pumps, but right now even though btc is over 20k in price, other cryptos are still low (OSMO for example).
