You probably did a good thing by selling your FUN tokens above 60. At least you have limited your losses from that decision.
Buying the tokens back is completely your choice but missing out on buying these tokens at a cheaper price would be a mistake.
You can at least buy some of the tokens back while saving some of the amount. You would at least be getting the premium benefits.
May be in future when the price increases your overall losses could turn into profits aside the the premium benefits.
The thing is, selling your fun tokens is not a bad idea, it's definitely a good one if you could flip it for a profit or cut your losses and look for something "better", there could always be something better. However, we should also remind ourselves that the amount of money you could profit from having fun tokens is technically "unlimited", because it will give you wheel of fortune rights and that means you could earn so much, like you could have golden tickets, you could win lambo, you could win weekly lottery top 10 place, you could have that few weeks in a row, or you could most likely just get satoshi or reward points. But if you keep doing it, you could recover for sure.
