that he bought Bitcoin at the time it was $65k and stayed few months till it got to $71k isn't enough reason to start showing people how potentially profitable investing into Bitcoin can be. I doubt he has even invested much into Bitcoin for such space of time for a different of $6k in Bitcoin price to have placed him in profit that will warrant him showing people his wallet.

The thing about going this extra mike just to prove a point to people is that it doesn't end up translating to them investing into Bitcoin and even if the person eventually gets convinced to invest at that $71k price, what do you think the person will be expecting in some few months or even at this point? He will expect Bitcoin to skyrocket into $120k and above and when he noticed that it's now getting bellow the amount his friends convinced him to buy, he will be made to explain tirelessly. Sometimes it's best we know that you don't go about trying to convince everyone to invest into something that's as volatile as Bitcoin when you don't know the emotionally strength of the person or you end up being blackmailed when they aren't able to HODL for long.  He has done a lot of harm to himself just by trying to prove a point and his safety is no longer guaranteed caus when you expose how much you're earning to people, they tend to feel this sense of entitlement as might tell everyone that you hold a particular amount of coin in your wallet which exposes you to big threat of not just hackers but physical robbers.
