It is true, that the value of the tokens has only go downwards and there is no real reason why it suddenly would go up. While I love freebitco.in, I feel like there is not a lot going on with the development of the FUN tokens and I think we all expected more from it.
The market isn't always rational and occasionally we get some really big pumps like the one from a few weeks ago when the price went up by more than double. This has significantly cut my losses and I expect that next year I will turn a profit. The token still needs more exposure and utility. I'm sure they're aware of some of these shortcomings and hopefully we will see some improvement in the new year.
That pump certainly helped and the value is still here than it was before, but compared to the BTC prize, the prize is still very low. Right now, it is again trading at around 18 satoshis, while when it got launched the initial price was above 100 satoshis. While we might see some improvement, I doubt that that price will be reached again anytime soon.
