That could be the possible scenario once the seller started to endure losses. But I doubt if he will invest immediately without studying about bitcoin on his own self, as every investment needs prior preparation and deep research before you finally decide to put your money at a risky investment.
Sometimes I wonder if investing is really the best step after some minimal introduction just as in the case of OP. U dont know if the narration is one that comes with some absolute truth but, it's just too early to want to invest almost immediately. You must have been very convincing in your small talks with your supposedly friend and I think you could do well in affiliate marketing with your talent.
Its nice to have brought your neighbour on board and most of all, introduced him to the forum but still, your guidance doesn't end there for him. There is a lot he needs to know and I hope you don't hesitate when the questions come pouring down because it does.
Seems like OP has its strong power to convince someone regardless if those being said are based on facts and are legit.
