@yhiaali3, maybe I misunderstood, if such things stay within the family it makes sense to some extent - after all, you never know who might tell someone else, and that other person then tells others about it and in the end everyone knows about something that should be a secret. Of course, things can always be "fixed" and it's very simple - you just need to say that that person changed his mind and didn't invest in BTC.
Be that as it may, I would still advise him not to invest his entire savings in BTC, especially not at a time when the price is this high. It's not that I'm giving financial advice, but maybe it would be wise to wait for a new bear market or try some experiments with the DCA method and invest a little every month.
