Even if you have bought more FUN tokens at the peak, you should continue to hold them. All the altcoins are moving down these days because the bitcoin is creating all time high every day. Very soon, the altcoins will make move and you will be in good profit in FUN token also. Patience and holding is the key to success.
Plus like mentioned you will get free stuff anyway, so there is really nothing to worry about. I see this fun token deal as something you could get VIP treatment for free, someone who wagers 1+ bitcoin and get a lot of advantages thanks to that (free lottery tickets, free lambo tickets, etc etc) and I as a person who doesn't have that kind of money could reach to him, I could gamble 0.1 (10% of what he gambled) and still could reach and even get more free stuff than him, how? Using Fun Tokens obviously. So long story short we are in a situation where we are capable of actually making a profit from something like this if we are smart enough.
Also all the small coins went up really high recently, but with this new BTC increase they dropped a bit, I am sure they will go back up very soon when the alt season returns, so buying right now is a smart decision.
