No, it's not. It is only necessary to the extent that people who already use it believe it is necessary. Some people like to pretend they're the trust police for Bitcoin, and bully people into thinking that their way is the only way to do things, because... well, because they say so. And they get all huffy and self-righteous and talk down to anyone who thinks otherwise. Lots of ad hominems, red herrings, circular logic, etc. It's a lot like a plumbers' union making rules amongst themselves about how they deal with each other, which is perfectly fine, and then some electrician comes into town to set up shop and doesn't join the plumbers' union - so the plumbers get all mad because the electrician isn't subjecting themselves to the little voluntary cooperative agreement the plumbers have between themselves. It boils down to this: You're free to do your own thing, but you can expect to hear a very small number of very loud but very impotent people making noise that amounts to nothing of consequence. Feel free to ignore them.

That said, you don't seem to be gaining much traction at the moment. I believe this has a lot to do with the marketing style you've chosen, which makes your site seem a lot more like a gambling site than it does an investment one. That, and the fact that you blatantly ripped off the Mt. Gox site design - complete with Mt. Gox logo - and there's not going to be a lot of confidence that you are a legitimate operation right off the bat. I, for one, have gone so far as to determine algorithmically how one might profit from your system based on the information available without opening an account, and while the trading system makes sense (it's really a simple over/under bet) the margin delta (2x on long, 4x on short) means you are giving yourself a huge advantage at the expense of site users and pocketing the difference. Anyone who does the math will quickly realize the house advantage is astronomical if a user/investor/gambler plays both sides. Add to that the "withdrawal fee" and I'm not surprised at all that you're having to beg for customers.

Sorry, I didn't even realize it was a "futures" market - there is a big space at top of page - perhaps my ad blocker is stopping it showing.

Anyway, good with a futures market. Predicting the future price of bitcoin is a very tricky endeavour.

Just asking ... are people really buying at $105 $106 when the price everywhere else is $100ish?

OK so it is loading normally now, hmmmz.  Nice site, congrats!

VIP bonus feature is nice.
