In 20 years, people will either be saying Remember when you could buy bitcoin for only 3500? or Remember when everyone lost their minds and spent millions on useless internet money?
There is only one question out of that two questions will be asked soon. There are no people know what will happen in the future but since we are already here, I will be biased on the positive one. This is also the same scenario with the Internet back way back '90s, a lot of people don't believe that internet will not work in the future but look, internet can be our necessity now.
