ARDOR is a very old coin, unless they close some deal (like NEM with Wechat) I don't see a reason for big gains.
" old coin "
it will go on mainnet on 2018 ahahaha
buying ardr now, before the launch and being and early adopter could give really good gains
understand that ARDR is a competitor of ethereum, with better scalability and without security problems
'Is there real development behind or not' what? ahahaha
it's on testnet now and the source code has ben released
