As you mention, a lot of alts have and will probably never go back to their ATH (allthough never say never), but the biggest benefit that the FUN tokens have is that they give you benefits such as the WOF spins, extra cashback, extra interest, ... With all these benefits, it will normally always be possible to get your money back and even make profit.
Some may be able to return to ATH or even exceed it, while others may disappear from the market and never come back. The list of coins on the market will be reset again with lots of new coins taking their new positions. So if this FUN token can increase in the next altcoin season, of course, the position of this FUN token can also increase and get a better position than before. And yes, with all that freebitco has to offer its members, this is one way to increase the number of FUN tokens we have while waiting for the price of FUN tokens to increase again.
