I recently converted a bunch of one coin to another using swapspace.co
Exolix
So, this was about a month ago after winning a street art contest and being flagged to hell for it. I changed all my staked tokens to get some Steem. The long and the short of the problem was that I changed out about 2,500 dollars worth and they only gave me about 1,000 dollars worth of Steem. Thus... poor exchange rate as my fee for using the service.
Cost me fifteen hundred dollars to move twenty five hundred on Exolix.com
Below is the last contact from them. I guess they are willing to overlook the whole case with the excuse that the Exchange ID is not from their system. It was a swapspace ID.
Either way. I will never use Exolix again for having stolen from me, then dragged me around for a month asking for hashes that are clearly visible on both blockchains.
