Logic behind this is there is no real hashing power, the admin of site makes money through ads of the sites, and reason there is 0.01BTC threshold is to minimize people doing payout, so less money goes out from admin, this means if a guy plays this game a month and gets bored and leaves, the ads you made for him went straight to admin but you wont get BTC because you dont have 0.01BTC in your account.
The site is from many ways from my view lacking important functions, one of them is SSL so we do know we can login safely, just aprox 20$/year for a cheap SSL man, not much u already got many ppl in site and do much earning with ads (dunno how much, compared to a yearly SSL you surely do more then 20$/year
)
It lacks speed, speed and speed, im bored of the loading screen where it loads and loads and stucks so i gotta refresh to hack GHs.
In short, there is NO real hashing power, btc you make here is most likely very little because you will be left out with minimum 60ghs (under 60ghs activates protection) and daily income with under 60ghs is very little, it's all with playing alot and doing it even on the phone when it is possible. Simple from my view, if it's not a scam (which i believe IS) then it's worth.
Good part is Admin doesn't want any deposit which is a big + from me to prevent ponzi-scheme or any similar scams, another thing is admin could be closing accounts with a excuse which im concerned about it.
Overall, it's nice but admin should decrease payment threshould to 0.001BTC, you do mention transaction fee, good, great, but hey, you can set transaction fees minimum and inform from website that it could take a long proccess to get confirmations, this way, both side is happy, but hey, we all know your plan. Setting to 0.01, with hack-able GHs (where there could be possibility that system automatically removes some GHs from ur account) and minimizing payout threshold so HE makes money instead of giving it.
Sorry for long post, and wooo! my first post.
