Scrypt hashrate is way too fragmented, you are likely to end up with way the heck less than half of the world's GPUs and scrypt-FPGAs securing your chain, and thus basically you are designing from scratch to be already out-hashed umpteen times over before you even launch.
It is irresponsilbe to deliberately set out to build an insanely vulnerable system given that the system will be dealing in effect with other people's money.
First figure out how to ensure more than half of the world's hashing power is dedicated to securing your blockchain.
Hint: look up merged mining.
Or, design and build an ASIC for a kind of hashing no other coin uses, then launch your coin after you have the ASICs up and running.
By the way this thread too seems like it is in the wrong section, I think you can move your own thrads so maybe don't bother waiting for a mod to move it to alternative currencies section, be polite and move it there yourself.

That is why we need a developer - to make it safe because we know that we can't guarantee safety only by ourselves.
BTW we have already moved the thread, thanks for telling us.
