so total in youre site database only 3 coin
yeah was working on it 3hours when I posted I plan to add all major coins also a converter list of exchanges etc as said its a side priject and will take a long time
for banners I may remove them dont know or only let one their is no design yet that will be last
if you want any coin calculator faster just post it and if possible for me I will add it
