Bitcoin Shows First Warning Signs After $15K Surge in 2 Days

Bitcoin experienced one of its most impressive price increases in recent history since Wednesday afternoon as it skyrocketed by over $15,000 in less than 48 hours to near $80,000 for the first time since mid-May.

The old saying, though, ‘what goes up must come down,’ has come into focus now after the asset was rejected at $80,000. Here are some additional warning signs that could lead to a more profound correction.

Whales Are Cashing Out

Such an unexpected price surge of over 25% in just days in times of market distress and lack of actual major catalysts aside from the US Treasury Department’s pivot caught many investors off guard, and some of the most prominent ones have decided to secure some profits. Perhaps the most obvious example was reported by Lookonchain earlier today.

A mysterious whale offloaded another 2,700 BTC for $212 million today. In total, they have disposed of 7,700 BTC for $576.6 million in just three days as the cryptocurrency’s rally began and it broke above several notable resistance levels.

The analytics company outlined another such example in which a whale whose address ends with bc1qqt sold 550 BTC for nearly $40 million, securing a profit of $4.5 million.

RSI and Market Greed

The second warning signal came from the Fear and Greed Index. As reported earlier today, the metric has skyrocketed alongside bitcoin’s major rally, surpassing 70 for the first time since October 2025. If you were in the market at the time, you definitely remember the calamity that took place on October 10; in other words, the last time there was so much greed across the industry.

Too much fear or too much greed typically leads to trend reversals, even if the current landscape is still not within the ‘extreme’ territory. After all, let’s not forget Warren Buffett’s words that investors should be fearful when others are greedy (and vice versa).

The third factor that could play out in the short-term is the RSI. More specifically, the 4-hour RSI, which, according to Crypto Rover, hit an all-time high on Friday after BTC’s surge to $79,700. Perhaps that’s one of the reasons why BTC cooled off immediately and slipped to $77,000 as of press time.

The Dark Horse

One cannot simply underestimate the power of this warning sign. His name is Jim Cramer. The famous TV personality, perhaps even more famous for his rather questionable and often wrong investment calls, advised a caller on Thursday to skip buying Bitmine’s stock and accumulate BTC instead.

History shows that when he makes a call, investors should listen. Often, to go in the other direction. Recall that Cramer said he would sell all of his BTC earlier this month – just a few weeks before bitcoin’s price explosion. We all remember what happened next. In this article, we have published a few more similar examples.
