Don’t ever try to “convince” other people to join crypto. Also don’t automatically consider them fools for not buying cheap and getting interested when it’s up. 

The truth is, if you aren’t genuinely interested in learning about it, and are just looking at the potential profit alone, crypto is a dangerous place and the chance they mess something up is sizeable.

Even though it’s been a great investment opportunity, you do not know what others might be investing in that made them not have time to get into crypto. 

They might have chosen to invest their time into building a business, starting a family, building a career etc instead. There are only so many hours in a day.
