I can't count my departmental mate that I have introduced to cryptocurrency, though they were all driven by the sweet gains they hear from people but after giving them the necessary digest and important info, they refer to be a long term holder than engaging in all this shitcoins that are usually introduced to newbies.
You should make sure that your mates understand what bitcoin is and how it works first. Then they will appreciate it more than the shitcoins, because they will realize the lacking of the latter.
Usually people lack the capital at hand to buy bitcoin because buying one bitcoin is not a joke, it is costly for an average salaryman from a middle class family. Therefore teach them about the divisibility of one whole bitcoin into smaller fractions and ask them to buy a fractional amount instead.
Giving and sharing this knowledge will make you feel like a boss and by the time you share this knowledge and the idea works for them, trust tlme, they will appreciate you the rest of their life and they will always consult you with new information or anything new things before they execute them.
True, but dont force them to buy anything, otherwise they will put all their losses on your head. You should only inform them so they can execute their choice but not make their choice by yourself.
Show them the charts and try to clear their confusion regarding bitcoin. This is how everyone can help possible investors into bitcoin.
