The untrackable transaction is one of many factor thats why Bitcoin still not legalized in many areas, and some of them use blockchain to hide their money from taxes. But as the time will go, Bitcoin will legal in many areas (with certain rules), i think the government is on thats direction, they just confused how to make the right regulation with it.
Many countries ban cryptocurrencies because someone loses part of their money due to cryptocurrencies. Scammers scam money in cryptocurrency.
But no matter what industry there will be scammers, I hope that all countries will legalize Bitcoin.
But the good news is that more and more factories, companies and supermarkets are using cryptocurrency to issue remuneration and payments.
