We already know we can't trust exchange sites as they could go gox any moment but yobit could just be different. They've been around for years and had been paying good to all who participated their signature campaign. I'm quite sure they are earning well enough not to go crypsy/
Yeah your right but not all.. maybe if the price ofbitcoin after block halving has been doubled maybe they will be run after price increase and sell and sell some altoins to other exchange sites so that they can make more money.. all online related in bitcoin is not trusted unlike exchange sites that accept paypal the deposit.. so the you have to power to dispute the site.. all trading sites are not too legit because this is all online base and no real identity from the owner of the sites..
But for now as i can trading there.. i think they have no plan to run because if you remember yobit is starting a signature contest and they are planning to change their signature.. and if im the owner of yobit i have no plan to run your coins because this is a passive income and even the value of bitcoin is increase or decrease im still making a money in my site..
If you are not believe better to save your coins to other wallet that you know that is safe..
exchangers don't run away because of the bitcoin price increase like what cryptsy did, they claim they have been hacked and they release some sob story and then try to show themselves as victims who can't do anything too.
you should never trust an online service (not only exchangers but any service) with your money and you should always cash out before it is too late and keep the funds with yourself and deposit only when you want to make a trade.
besides the signature contest and all the things like that does not change the fact that they are a bad service, and the customers (we who are using thier service are not happy with how they handle things, like crappy support team or wallets that are in maintenance for over a week.
