well then good luck with that, you'll need it...

if you really just wanna learn about crypto and coins, go ahead and ignore the "scam coin!!!"-mob.
but if you hope to start a new successful coin better but some features in it that aren't there already. no need for another bitcoin clone with different supply amount and block time.
also, i suggest a beta test launch first with volunteer miners and trashing the coins afterwards. cause beta testing is what developers do...
