I wouldn't hestiate using the "next Neteller" if the books sign on. I use Neteller to transfer funds from book to book, so the time my money actually sits in Neteller is a matter of minutes, or even seconds. The books are the ones that need to be careful, so if they check them out and sing up, then that's good enough for me. If you manage your money correctly you have nothing to fear. If it turned out to be a fly-by-night operation you would have to be unlucky enough to have your money in there at the precise point in time in which they cease operations.
