We can say that criminals can use cryptocurrencies because of its anonimity transactions. Well in our country, we can't convert directly crypto to fiat. We really need valid Ids to withdraw our cryptos in fiat so how criminals can use their crypto? Unless they have relatives and make withdraw for them. And about the thieves? If you just keep your private key very well no one can steal it.
KYC is needed for local exchangers, and this can reduce the concerns that have been circulating so far, namely money loundry, narcotics, etc. hopefully the government understands it and provides policies that support cryptocurrency. and about the wallet, it's actually safe, as long as we don't do carelessness. fiat money even if we are careless will certainly harm us
