my question is, can a customer cancel an order if the price falls dramatically?

If yes, then it is all fair game. If not, and they only cancel when the price goes up, while forcing you to buy even if the price bottoms, then this is fraudulent behavior.

These sorts of myopic arguments abounded during the early 1990s too. Modems take forever. Downloading a tiny image is too slow. Who wants to watch 10fps 320x240 video that needs to re-buffer every 20 seconds...etc.etc.etc.

Have some vision. Think a little bit. Realize the positive-feedback-loop dynamic of phenomena with strong network effects. Realize too that bitcoin (finally) has significant mindshare with really talented, accomplished people. Innovators are innovating, VCs are investing, and better, far more professional infrastructure is being built every day.

This is happening, and those with myopic short-term vision will be left scratching their heads as to how it all passed them by.

Interesting.  That's good to hear that bfx is on top of wires!!!

Are you saying that bfx has the power to move a market because they operate like 40-55% of btsp's trades?

how are you able to offer 5 % lifetime rebate when they only offer 10 % for one month for affiliates?

If you can't sell it, you should consider using it for staking purposes.  I'm assuming you're selling it because you don't have the time to play anymore.  Using it for horses would give you a pretty decent stream of income.
