However, if it is legalized or allowed to invest and trade crypto, then it will make various things related to crypto easier. For example, if there is legality, the country will allow local exchanges to make it easier for its citizens to transact, will expand the forum for the community to relate to crypto, and also several regulations that benefit crypto activists.
Yes that's basically the edge if the country generally accepts it. It's even quite difficult to trade in a country that doesn't allow the use of crypto. Basically most crypto trades even require you to deposit some coins before you can trade.
Even when you intend to make use of fiat you will still need to do p2p most times to get crypto first before you can trade. Another down side is you have a high chance of being offered bad rates this is because there are just few vendors available.
Yes, everything definitely has its pros and cons. However, if it does become legal, even within certain limits, at least, recognition of the legality of crypto can provide a fairly large profit. But one more thing, unfortunately, usually this will also affect the government's decision or consideration to collect taxes from crypto, from crypto transactions. As happened in my country, where after crypto was legalized, then in some time, in the end, the tax was imposed during trading through local exchanges with a certain percentage. Well, again, everything has its pros and cons, including this.
