Personally I think the sweet spot for their premium membership is around 12,500 FUN tokens so I have around that amount of tokens. Will not buy nor sell any tokens as my average price is around 60 satoshis or higher (first batch I bought at around 100 satoshis). Just keep holding them and in the long term, I will always end up in profit.
You will be only in profit if you manage to win good amount from the WOF spins and continue the locking process of FUN token. 12.5k is indeed the standard amount of FUN tokens to be hold for enjoying the premium membership benefits. Now your FUN token value is almost 72% down from your average buying price. It will take around two years locking period to make profit if FUN can't recover it's price.
