A friend of mine who we started this crypto race together over trusted his security agency friend by telling him about how he is being Invested on Bitcoin and how he makes daily profits on trading and while that of investment is set for his retirement, the trading provides him the regular expenses.
Yeah, I know the world is in a precarious situation now and things are really bad but then someone has to trust someone. Like OP pointed out about his friend, the security guy had been there for him in good and bad times. So, I don't think it's such a bad idea to confide in him. The only danger will be if he revealed all to him. There must be something he should hold back on. Reveal some, don't reveal all; especially if it's the part that won't help his course.
He further said he told him about his engagement on Bitcoin just in case he has a query in that the public or even the security agencies do figures people who participates on Bitcoin or cryptocurrencies are suspicion of being scam.
First, Bitcoin isn't outlawed in Nigeria at the moment. It's legal, it's just that we all are still skeptical about government's view on it, knowing how erratic this government can be on policies.
So he (my friend) was like an already made an open entry statement about his engagement with crypto on or before (just in case) he is being probed of illegality so, his friend can always stand to defend him after early notice.
It has to be formally written for it to be admitted as a statement in the face of the law. So, his verbal confessions to his friend is immaterial. Besides, crypto activities are recorded and can be traced from the Blockchain. He doesn't need to panic if shit hits the fan. All that will be needed will be to trace whatever information he gives on his crypto dealings.
