I whant to sell my reddcoins

You can do this at the many exchanges you can find by googling online. Or do you have any reason why you would not like to go to an exchange?

Becuase to sell there first i have to ger btc

You dont need btc before you can sell reddcoin. You can use this one for example:https://www.litebit.eu/en/sell

Why would you like to sell them however?
