Only scrypt hashing algo?
If yes, price is too high. walletbuilders is more cheaper.

my service include block explorer install , that service only worth more than 100$

it costs 400$ ?
I think, no. And will you provide source code and linux daemon? For exchanges this is important.

price change to 250$

is there any other algo for choose ? POW/POS ? bookmarked this ann and keep watching , the price is OK for me ~~~

thank you , for now , i want to create scrypt only because i have more experience and skills on this algo
