locked funds mean something like this: When there is a high demand on thing X and it's not available, the price on thing X increases.
I don't think it's as simple as that in reality. If you look at the FUN token price you'll see it didn't change since the beginning of this offer and is still at 49 satoshis. Usually this kind of investment is offered more to create a craze and to attract new investors than to deter previous ones from selling them.
