First of all, I am sorry for your loss. It really is a shame you did not research Fixed Float before sending your Bitcoin and not only that, Trocador also cannot be trusted. The chances of you getting your Bitcoin returned are zero therefore (as unfortunate as the situation is) you will have to try to move on from this.
You have add another scam to the list by Fixed Float, hopefully others will read this and make a decision to avoid them.
It's a shame I did not look them up on this forum before the exchange, as I would have seen all the others that they stole from.
