To my knowledge the first cryptocurrency was Bitcoin. Do you agree?
Since 2009 Bitcoin was launched by a person on behalf of Satoshi Nakamoto (aka) there have been very many positive things that have been obtained by people in the cryptocurrency space. Because Bitcoin has a limited stock, thus making the price of BTC expensive and then in anticipation of people being able to invest in crypto, Altcoins were born as an alternative.
Please give suggestions if my post is not correct.
Yes all except El Salvador are either not classifying Bitcoin as legal or illegal. Some are anti-Bitcoin, but others are just in the gray area where they classify Bitcoin and other cryptocurrencies as securities. Because it is decentralized, Bitcoin is prone to money laundering without any third party interference to approve or reject the transaction.
There are various reasons why the state has not legalized bitcoin, including as you have explained, besides that many say bitcoin is close to terrorist activities, and of course money laundering. on the other hand, because bitcoin cannot be controlled, it is considered less profitable for a country, but I think this is just a matter of time and the situation is not right, of course it will develop according to the situation of the times.
