I bought into this a few days ago. I only bought 100 GH/s because I have this feeling that I wont really make anything on it. In fact I would be happy to see just break even in 5yrs. It all depends on the difficulty not increasing drastically I think. This term it doesn't look like it is predicted to be a big increase so I shouldn't see a big drop per day. If we get a few terms with bog increases I may not have any chance to ever make it back. Either way it will be an experience that I will learn from one way or the other.
This is the problem with buying such a long term investment in cloud mining or any type of mining for that matter. As it is now the difficulty is doubling roughly every two months, in other words your expected revenue is going to half every two months (assuming that your provider does not charge any kind of ongoing maintenance fee, if it does then your drop will be more every two months). The later part of your contract will see very few results.
My thinking was with the .3btc i spent on this contract... What could I have bought really to get into mining with such little funds. I mean, for me to buy a miner doing 100gh/s would cost me more then .3btc. I will still only get 100gh/s so all I am losing is the paper weight after it costs more to run then it can get mine in coin, which I imagine wont be long. Like I said it is more of an experiment for me. I will not be reinvesting along the run I am just curious if it will eventually give any roi at all.
Well the morning I was able to buy 200 GH/s for 0.58 BTC, then I sold it all a few hours later for .62 BTC. That was PETA on HavelockInvestments.com. If you are playing with small amounts and willing to wait a bit you can make BTC there. PBMining isn't the only game in town and at least there you know what is real and what isn't.
I started there with .4 BTC, built it up to about .6 BTC then I added 1.85 BTC more and did some bigger trades. (Total deposit in was 2.25 BTC) I have taken 1.0 BTC out and my balance there is still 2.14 BTC. That is just over four weeks to make 0.89 BTC. I've been sticking to mining stocks that pay dividends, there are only a few.
Okay, it might be just luck, I've lost big before on stocks and it could happen again. However, the point is PBMining isn't the only game in town and you don't really know what you are getting with them. In all fairness I watched Havelock for about 7 months before I tried them and I think they used to be a lot bigger. There are other places too, like CyptoStocks, but I'm still just learning.
