Sorry for your losses, but I'll have to agree with @NotFuzzyWarm here. Since it's illegal to use Bitcoin in your country and you do acknowledge that fact, no matter how much “liberation” you ensure with p2p trading, you're a criminal, because your country's government disagrees with what you do.
It depends. Like in Nigeria, CBN ban cryptocurrencies but using P2P is beyond what they can ban, such ban should be from the legislative arm which would be signed by the president. So, we do not know how the ban is in their country. In Nigeria, we trade cryptocurrencies legally with a secondary school and a hotel even later accepted bitcoin for payment after the ban.
Even if cryptocurrencies are legal in their country, that will lead to loss. Assuming he used exchanges like Binance, it is possible for him to still be able to appeal that the money was sent from a scammer, but provided if the criminal has not withdrawn the Bitcoin. If they also make use of direct P2P, the transaction can not be reversed. So, it can still result to loss irrespective of Bitcoin legal or not in his country.
So far the name of the platform for the p2p is not mentioned, likely such platform are not recommended, and this is the risky/faulty part.
