Bitcoin recorded a total of $169.6 billion in whale transactions over the last seven days, according to ITB. On-chain data shows that an 11-year-old whale address with 2,700 BTC, worth over $257 million, transferred the Bitcoin holding to another wallet for the first time since December 2013, hinting at a potential selloff due to the 157 times return. The whale accumulated the Bitcoins when the price was hovering around $625 for a total of $1.68 million. Bitcoin is hovering at $96,500 after gaining 1% over the past 24 hours. Its market cap surpassed the $1.9 trillion market again. The increased exchange inflows could trigger FUD (fear, uncertainty and doubt) among retail investors. However, a spike in whale accumulation could shift the market sentiment and bring buying pressure. At this point, the next major bullish catalyst for Bitcoin and altcoins would be the potential U.S. Federal Reserve’s rate cut — the FOMC meeting is scheduled for Dec. 17 and 18.
