Hi friend @darthgexe, thanks for visiting.
Just one detail to keep in mind, as @sames says, blocktrades is not completely decentralized. We are not doing peer to peer transactions, everything goes through the blocktrades account and we adjust to their taxes. Of course, all this does not mean that it is not a good service that we can use.
Sure friend, the important thing is the safety and speed in which we can perform any operation.
Thank you!
