This might suggest that there will be a surge for BTC and other cryptocurrencies?
The amount is good but not strong enough to influence so even if owner wants to sell, I do not think it can affect the price. It can onlotc trade with an etf y influence low volume small fishes and shitcoins. Anyway, it is probably exchange's money and just sent to the wallet to hold it.
Either that or its a huge exchange for an etf or something that is hoping to be approved.
Tracing the chain and seeing where the funds initially started seems quite a good idea. They may all have been from the same miner or service.
