According to Ki Young Ju, the withdrawal “went to custody wallets that only have in-going transactions,” and was likely an “OTC deal from institutional investors” based on several identifiers. He also pointed to the fact that the split of a 15,000 BTC wallet into wallets containing 1,000-5,000 BTC increases security costs. Furthermore, most of the internal transfers are done with round amounts, like 1,000 to 5,000 Bitcoin, while this transfer included odd groupings of 1,265, 2,391, and 1,957 BTC.
As to why Coinbase outflows are a bullish sign for the top cryptocurrency, Ki Young Ju linked to a previous tweet from Dec. 18 which states that “if Coinbase moves a significant amount of Bitcoins to other cold wallets, it indicates OTC deals” which are non-exchange transactions.
He said: “Since the price is eventually determined on exchanges, massive non-exchange transaction volume is considered as a bullish signal. These transactions include OTC deals.”
The slow inflow of institutions into the cryptocurrency sector is helping to increase the legitimacy of the crypto sector as a whole and appears to be providing a certain level of support for the price of BTC as the available supply continues to be locked away in cold custodial wallets.
