>This means, that Bitcoin is something you wouldn't want to store value in for the long-term. I can think of a reason you would want to. Bitcoin is strictly supply-limited, and all fiat currencies are not. One might decide that, despite Bitcoin's volatility, the expected change in unit value over time is higher than that of any (inflationary) fiat currency.
With the difference that other fiat currencies are spectacularly unlikely to be declared illegal in your jurisdiction. There's a non-zero chance of your "bitcoin stored value" being about as desirable as a few suitcases full of cocaine, if your local laws fall that way. I wonder if tip4commit have even considered whether any of the unsolicited donations they're collecting for are intended for residents in any of the…
So we've gone from "it's volatile" to "it's maybe, potentially, illegal at some point in the future"?
Well, there are a few reasons I wouldn't be worried about this. A) It's not likely that Bitcoin will be banned outright in most countries. B) If it were to be banned outright, you'd likely have plenty of notice and be able to sell it before the laws took effect.
Also, it is not as if the project is actually sending Bitcoin to the developers; it is simply making it available for them to claim. A more comparable analogy would be if a sweepstakes in Colorado told me I had won some free marijuana; even though marijuana is illegal in my state, I am not legally culpable unless I actually claim the winnings.
