Bitcoin (BTC) showed signs of a resurgence on Jan. 22 after a trip below $30,000 produced fresh buyer support.

BTC price seals 8.5% daily bounce

Data from Cointelegraph Markets and TradingView showed a stronger trading day for BTC/USD on Friday, with daily gains at 8.5% at the time of writing.

The turnaround follows a turbulent 24 hours in which Bitcoin slid to $28,950 — a key level when it comes to support from whales and only its second dip below $30,000 this year.

At the same time, MicroStrategy, well known for its ever-increasing Bitcoin treasury, confirmed that it had purchased 314 BTC to bring its total hoard to 70,784 BTC.

"Microstrategy just bought 314 more #Bitcoin for $10M. @michael_saylor bought the dip," Twitter-based information resource Documenting Bitcoin summarized, referring to the company's CEO, Michael Saylor. 

The latest buy-in came at an average cost of $31,808 per Bitcoin and joins asset manager Grayscale's ongoing purchases that defy overall selling action in the past few weeks.

All eyes on whales at $29,000

Among other major BTC investors, meanwhile, interest remained focused on the area at just below $30,000. 

According to monitoring resource Whalemap, that area is crucial to hold in order to avert a further price dip on BTC/USD, one that could take the pair closer to $20,000.

"Falling below $28,727 and consolidating there will give us another big drop to at least $23,818," part of a series of tweets explained, along with an accompanying graphic.

"Not many supports below $28,727 right now, so if we start consolidating there, it will probably bring BTC all the way to at least $23,818," co-founder Artem Lazarev told Cointelegraph.

"$23,818 is not super strong but nevertheless should provide time for BTC to reassess the situation. Otherwise, $19,322 is super strong and a level for which big guys are setting their stoplosses probably."
