Well, some banks are now accepting Bitcoin deposits. Institutional investors and governments are also accumulating large amounts of Bitcoin. We already have centralized exchanges forcing users to comply with KYC to buy/sell BTC. With strict regulations in place, making Bitcoin legal tender should be a no-brainer. Especially when most governments are collecting taxes from it.
Deposit your bitcoins to an account on a centralized exchange is already risky but deposit your bitcoins to a bank account is more dangerous. At least in the present, banks are more regulated than centralized exchanges and you will have higher risk of having problems with banks than with centralized exchanges.
It's good news for people who love banks and don't want to migrate from banks to centralized exchanges, decentralized exchanges and best with non custodial wallets to have their "own banks".
As a Bitcoin fan, I of course fully support the idea of making Bitcoin a legal tender, as El Salvador has done. Several other countries have shown a friendly attitude towards Bitcoin by making it a national reserve asset and facilitating the crypto community to trade Bitcoin on futures exchanges regulated by trading bodies under government control. Currently, Bitcoin has experienced rapid progress, the government has legalized Bitcoin as an investment asset, but it is still limited or not legal as a legal means of payment.
It's truly good for Bitcoin adoption but Bitcoin users must learn and know fundamentals of Bitcoin. This is neccessary for them to understand magical avaialble things which are provided by Bitcoin, free to access, and safe for their fund.
People who love banks, deposit their bitcoins to bank accounts, will soon have to learn difficult lessons with their own coins stucked, frozen, seized there in the future.
