i guess the best way to avoid the scammers is to use exchange ? or simply create blockchain wallet and swap it there. its free
Yes how come a small amount of transaction to be made is not butt hurt to your side. This should be done in an exchange and you can see directly sell that one put it into order place or even buying place for the crypto you want. Do not bother escrow service provider here. By the way your post looks scam maybe you have something to achieve like scamming.
