what do you think
You're going to have to offer some examples on this. I'm not sure what you're getting at, there are too many ambiguities. Perhaps you could link to some direct legislation and explain their effects?
For instance, Nigerian government made a recent policy that band crypto currency and its usage in the country,they even went to the extent of blocking all accounts that have ever engaged in crypto transaction but what did that lead to,
it made it to be scarce in the country and all those who had it inflated there prices by adding additional amount to it and it became the most sought after crypto and its only sold on peer to peer level now
Yes the government made that move to stop Banks and other financial institutions from dealing with cryptocurrencies but I wouldn't say that this lead to it been scarce and increase in the price. Firstly, most Nigerians deal their crypto in exchanges and I strongly believe Binance is one most Nigerian deal on and even had a local currency pair there so if all bitcoin and other Alts been traded on exchange how was there a scarcity of crypto? because I never read any thing relating to scarcity.
Secondly, I also didn't read or hear about increase in bitcoin price because of the Nigerian government policy. Even though the policy was in place, some people were already use to using p2p and just became the go to option since the announcement.
The only thing that the policy changed was just your ability to do a direct withdrawal to your back account from the exchange nothing more.
