- Hashlets can never be unprofitable/never breaks down
By never being unprofitable what they mean is that their hosting fee will ALWAYS be less than the miner makes in a day. Meaning that if the miner gets down to less than $0.08 a day, they will reduce their hosting fee. It never breaks down because most likely we are buying shares of hardware power that they maintain for us
Nobody can guarantee miner's profitability unless the hardware and electricity comes for free.
Ponzis always pay the first (except cryptcominer

)
You probably will have ROI but many people won't because this is a scam. If you feel good about it go on.
Do you understand that they are not guaranteeing that you will make 100% ROI? They are ONLY guaranteeing that their fees will always be less than the amount of bitcoins mined. Meaning that one day they may have to drop their fee to $0.00 so that your $0.000000000001/day is still "profitable". Don't be tricked by their wording.
