Why not ask this question on Nigeria local board?
How can we know this is true or not? Let them report to police and it would later be taken to the news and beel seen. That would be only when people will know that you are not lying.
and if you weren't lying what's stopping the kidnappers from demanding crypto directly?
This is ridiculous, I feel you just made up this story the same way you have been making others.
Like a self-made story to me too unless I see it on the news. But abductors may not have the technical knowledge about bitcoin and other cryptocurrencies.
