Hi Quontoloue,
30 USD is the minimum investment (200 GH/s), but the larger amount you purchase, the cheaper per unit you'll get.
In terms of investment return, it really depends on the overall mining difficulty and the Bitcoin vs USD exchange rates.
Just to give you some contexts - on July 10th, I bought 1000GH/s plan and got Bitcoin worthed 0.009 USD, which means it'll roughly take 166 days to break even on for my investment
IF the payout and the exchange rate keep the same. I guess every Ponzi scheme will claim they're legit at first LOL
As a reminder, WageCan has been around since 2014 and keeps adding up other services. And we have offices in Taiwan, Estonia, Los Angeles.
Not to mention this time we partner MyRig, formally known as Bitmain Warranty, to take care the machine for you.
I'm happy to answer if you have other questions.
