I am just curious how did he lost all of his money in link? LINK didn't went down to zero so it's impossible that he lost it all? But if he is playing his LINK in Futures trading with high leverage irresponsibly it is his mistake not on link. If that is the reason why he call link a scam he's an id*ot. What if he lost bitcoin on trading too? He will call bitcoin a scam?
The result is negative and it is because he never knows crypto trading and sees LINK doesn't have that potential but a dumping project. It is so sad that someone had lost their money for such stupidity and make an investment without knowledge is highly getting risk and probably it end up nothing.
I don't see that Dave deserves those losses, He's in business and surely he has at least a few knowledge in terms of investment but it gets wrong is that he never knows more about LINK and bought it. But I don't believe that he loses it all, not really acceptable and can be faked. It for sure, Dave saves some only he doesn't want to tell what it brought him that sad ends.
