I wonder what are you waiting for with those 666 WoF spins

.I don't know your plan at Freebitco.in but if I were you I would spin them all,and use all the RP points I would get to use every 24 hours the Free 1000% BTC bonus and use those Satoshis to increase the stack of FUN tokens.Most probably I am guessing you have a lot of FUN tokens since you are at 666 spins already and that can be the best strategy,right now they are just above 1 cent but imagine if they go like 20 to 50 cent,that is a considerable amount of money you can get if that happens.
Whatever your case enjoy your spins.
A 20-50x increase is not likely to happen, unless Bitcoin goes up 100x, so it is better to stick with bitcoin than go chasing after the next get rich quick token.
