Who is the whale of Bitcoin?

Many people believe that Bitcoin has no whale, and more consensus has achieved it,

because raising 100 dollars may require thousands or even billions of funds.

Recently, I've been watching Tether continuously issuing USDT, in November alone 7 billion USDT was issued, nearly 50 billion RMB, and I increasingly feel that,

the whale of Bitcoin is actually the USDT issuer,

Is Bitcoin useful?

Decentralization, blockchain, these have already been manipulated and deviated,

The only use is global circulation, not subject to bank control. #BTC何时破9万? $BTC $ETH
