If you're going to use it for anything adult-related, you should check out Sexcoin. It's marketed directly as a coin for the adult industry.
Why would they need to use it? A name doesn't matter. What does Sexcoin offer that BTC doesn't?
If there is any amount of coins, quoted on Crypsy, they are all OK.
I need instructions, how models/online tutors can to earn they all with shortest transaction confirmation, or if there some fastest coin, that permit make it in shortest time.
