Bitcoin billionaires continue to accumulate during the dip. As Bitcoin (BTC) filled the $42K December price wick this morning, Bitcoin whales were busy stacking sats.

One address belonging to Binance added 43,000 BTC on the 4th of January at an average price of $46,553.68, bringing the wallet’s total value to $5.5 billion.

Elsewhere, the third-largest Bitcoin address continued its spending spree, adding another 551 BTC since Cointelegraph last reported it bought the dip, just two days ago. The wallet continues to aggressively accumulate in the $40k range, now owning a total of 121,396 BTC or roughly $5 billion.

There was some consternation on social media platforms about the wallet owner behind the 43,000 BTC buy, but Binance confirmed ownership of the address in a Tweet sent out in 2019.

The wallet address’ “3LYJfcfHPXYJreMsASk2jkn69LWEYKzexb” intended use was for the company to issue a number of crypto-pegged tokens on Binance Chain, starting with $BTCB, a BEP2 token pegged to $BTC.

However, the wallet appears to have evolved into a cold storage wallet for the world’s largest cryptocurrency exchange. In a Tweet by advanced blockchain tracker @whale_alert in April last year, the wallet was again labeled as the Binance BTC reserve wallet address.

Although the wallet has been used to mint 13,001 BTC onto the Binance Smart Chain, the owner has never sold a single Satoshi. Since June 17, 2019, it has accumulated a whopping 116,601.13647202 BTC.

At the time of writing, the wallet is valued at roughly $4,982,770,577 or just shy of $5 billion. Talk about diamond hands.
