Crypto analyst Killa says Bitcoin's bottom has formed and estimates the maximum pullback in this bull market at about 10% to 15% as prices move from current levels toward $126,000. He says that if Bitcoin first forms a local high near $87,000 before falling further to just above $70,000, that area could mark the bottom, prompting him to substantially add to long positions (bets on price gains). Bitcoin is testing a key area around $80,000; holding the previously broken range high could allow the uptrend to continue, while Killa says he would consider short positions only near $90,000.
