What you will do if that thing will happen someday??
If that thing happen, I think it is going to be hard to gain more profit in another ways. Thise people who are depending on it will probably gonna jave a hard time. A lot of people are hoping for it. If that disappeared I will lose all my profit, and not only me but also me but all of those people who hold their altcoins for a long while. And there are big names who are holding some altcoins or maybe they are the one who create altcoins and if that happen their business will end and they wont let that happen.
I think it's not about you losing profit dude, because you can find another job to gain profit right? it's about the future of cryptocurrency? very likely all coins die or disappear, but see many people are very interested in the idea of cryptocurrency in particular bitcoin. I think the possibility for cryptocurrency to disappear is very small #IMO
