Be diverse if you are starting in cloud mining, any one of them can go in any direction on any given day.
Spread out your risk.
I agree that it is wise to spread your risk, I have Gaw Hashlets and Ltcgear shares I also have 2 Antminers at home, I would do more hardware mining if the electricity was not so expensive!
How are the GAW's Hashlets? I see people recommend them a lot. They are talking about 40% ROI from Hashlets. Are they really that good?
I bought my Prime hashlets whilst they were $16.00 and also some at $20.00 and $25.00 so I have already done well as the price has gone up to $50. Soon when they sort out all of the bugs they are having currently they will open up the Prime buy back scheme. Josh intends to pay 80% of the current selling price. So anyone that bought them in the early days will ROI instantly! As for now Zen's are your best purchase IMO and you will ROI with them as the pool pays well.
I did make my ROI on hashlets if i sell them on the market, but i managed to get it more because the market was new and i made some good deals. Buying cheap and extremly cheap from sellers making mistakes. I bought 6 Zen Hashlets for $13,33 in total, while 1 Zen Hashlet sells instantly on the market for $19,95 including 5% fee. So i can sell them for $ 19 each
I bought some legendairy for below $ 80 dollar and they sold for $99.75 (+4.5 fee for the buyer, so i get earned 95 for them)
I invested a total of 0.5 BTC in GAW and have 0.3 BTC in my account already AND i have 1 legend, some Zen's, some Waffle's and 100 GH genesis
So i can almost withdraw my 100% ROI, but i'm addicted to zencloud now
