Indeed everything is a gamble since we are not certain if our investments can give us good return. That's why it's a must for us to do our research for the possible outcome that might happen because not all the time we can have positive result. Anyway, I believe diversifying our portfolio is a wise decision, it's just depends on us what coins to choose aside from Bitcoin and other established coins already.
Regarding FUN, for me it's a good investment for long term but much better to have less expectation. For now, just enjoy the benefits of holding FUN on Freebitco.in since it's your edge to other gamblers who are just there to play and don't see the importance of holding FUN especially if you're a regular gambler on the said platform.
Agreed, I don't really look at the price of the FUN tokens as they will need to do something before the price will go up. It is a good long term investment and with experiments as Uneng is doing, we are able also to track how long it takes before he gets his investment back.
