A sell off here could see a frenzy towards the 200 ma which is where buyers are looking to sweep up cheap coin. Current price dip at the 200ma is around 35k mark which could results in a 45% dip in price from the most recent highs. This isn't uncommon in the world of crypto, however with the recent power of institution backing BTC at any given opportunity a Dollar cost average approach would be more suited going to dips like this.
