most probably their first strke is going to be banning all these altcoins.
That's true, and I have started to see that where I live, the government is more actively discussing cryptocurrencies in almost all media channels, especially on television, they are intensifying the release of digital banknotes and satirizing existing cryptocurrencies. I was really worried and the discussion resulted in an opposition camp that is us cryptoners who are still against and don't expect the blocking of crypto exchanges in my country.
4. Yes, we are all worried about bans, restrictions on Binance's activities in Japan, etc. last days, etc. But simply banning BTC, XMR or ETH or BSC may not be enough to keep them out of use.
In the event of a ban, it is anonymous currencies like XMR or ZEC that will take the leadership from BTC in their capitalization. ETH and BSC will simply go to negotiations with the authorities, preserving their real mechanisms by the crypto economies DeFi through an agreement with the authorities.
At the same time, it is also important that only 2-3% of users need anonymity, and 95% need the DeFi crypto economy, and only about 1-3% are Bitcoin maximalists who use now BTC not only for the sake of crypto-gold, namely because of libertarian idealism.
