Trader Killa said Bitcoin's bottom has formed after the price reclaimed the short-term holder cost basis, a metric tracking the average acquisition level of recent buyers. Killa previously said, when Bitcoin was at $65,000, that recovering $67,400, trading in the mid-$75,000s and holding above that cost basis would confirm a bottom. Before Bitcoin can rise to $90,000, however, the price must first break through the $80,000-to-$83,000 range.
