If the dev do the job ,why some guys can't accept his work worth 7 to 10 btc? Don't be so mean. I think it is the time to invest and dig more.
If the author has been doing development for the coin,and work hard for it's furture,it worth more than the value of 7-10 Bitcoin, but the problem is now authors always develop a coin, sold out all the primine coins within one week , then went away ,bulid another coin, this is pure scam, too much these authors now.
