I am not really type of person who is giving financial advice to anyone because investments always associated with risk factors so insisting them to invest on investments can backfire at us if it didn't go well.

But I helped them with their purchase once, by helping them to introduce to an actual exchange and how to buy it also explained the risk factor and taxation aka everything they need to careful. Also recently my uncle asked me how my investment in bitcoin is doing I said for the recent past weeks bitcoin is being highly bullish and he was happy about that.

I asked him whether he want to invest or not?

He clearly said no, and he is the kind of business person whom I respect and let him be his way.
