Let`s have a look for example to Hashocean`s userlist:
sunpower18*** (11/14/2015) 312 415 KH/s 350.27035572 BTCAny questions? Do the math

As I wrote and write every year there are some very simple rules to become ri(t)ch with all kinds of BTC-investment [Ponzi-shemes]:
1. Quick-in -> quick-out
2. Spread as much you can (downgraded in classes of risks)
3. You have to be ri(t)ch at the beginning, because money only comes to money (btw: actual CLDMine is down/death, but I got all my investment back as shown on their goodbye-page and in my wallet

)
There are allways two kinds of loosers:
1. Guys who ignore the simple rules
2. Guys who never invested
So my tipp fpr noobs are:
1. Withdraw as long you have not your investment back on your wallet
2. After full ROI reinvest max 50% of your dayly income
