sure. there are many other similar companies that have sprung up with time.I was with one, FTMO but didn't pass their challenge because of their rules. i don,t think they mean well for traders though. I presently i'm with BluFX for 4 months now. Its been a roller coaster but i'm now profitable and have made withdrawals. I use MT4 platform, so maybe things have changed with time.
I have checked topstep and the rest, i see that they run with demos to test you out or something but blufx uses real money. are you sure about this? could it be a demo that is somehow made to be tagged as real?
