One way is by educating them on the technology.  No doubt the number of crypto exchange users have dropped over the last 8 months but let me tell you, these are the newbies that went fomo during the bullrun.  Chances is that they don't even know what cryptocurrencies are.   They were only in for the money and when they started losing, they cash out. 

But for people like us, we understand what crypto is. We understand what blockchain is and that's the reason why we are still here!
