So many anti bitcoin laws and policies that seek to undermine the existence of bitcoin have been made by government and countries all seeking the centralization of currencies within it region and since bitcoin is a decentralized digital currency most government are against it.
Nothing to do with conspiracy theories, governments are simply trying to regulate them (or even prohibit their use) in an effort to apply taxation on people holding and dealing with cryptocurrencies. Cryptos are providing us a way to hide income from financial institutions and the government itself, they are losing a huge deal of money that way.
It's the main reason I'm not depositing my cryptos to the bank, I've got a decent amount of money on two separate wallets, if I were to deposit such amount, I'll have to declare them as income/earnings.
