But at earntomorrows go-down it was part by part. I had 2 accounts. The first got shut down and the other one got shutdown 2 weeks later. I was able to achieve roi with that left account. A few days later the account of a friend of me got cleared aswell. So it's not so unusual to collapse time by time.
But i don't think the end is near now. Reward increased... Why they should increase the reward to blow some extra money out before they shut down?
I don't think that rewards increasing or decreasing can be considered a clue, since most people will just reinvest their rewards and stick around "trading numbers that don't mean anything". The site will crash in 2 cases, I guess:
When an amount of people owning more than half of the tradable hash decides to sell it all and cash every BTC out (highly unlikely to happen);
When the admin decides to shut the whole thing down;
And also, increasing rewards might be a manner of increasing the ROI time stated by their calculator and, therefore, attract more people.
For me, it is just a bet. The site crashes down all the time but always comes back; Hash prices are extremely mercurial and the market is easy to manipulate... I cannot see a pattern that shows the website will be shut down or for how long it'll stick around.
