I would stay away from SPRTS - it is highly, highly inflationary, and the blockchain is unstable, so I am not sure how much longer it has to live. You don't want to be stuck with millions of coins that have been delisted from every exchange, in a wallet that won't sync!

Of course it has survived this long, so possibly it could last longer than I predict ;), but even so, it is hard to imagine the price rising with the ridiculous amount of coins being generated every day.
