It's fine, they are a big wallet provider and already providing services for sellers to accept the various coins, that's what we were using them for. This is a new initiative of theirs, I just signed in to my wallet and the coins were there, credited.

As to how much the coins will be worth in a few months, I don't know, but there's nothing to lose and they do seem to be providing useful services at a low cost. E.g. we are using it on clickforafrica.org and they charge us 0.5% for deposits and withdrawals. all internal transfers are free and now they seem to be going further with interesting ideas.
