Stay away from it, it is almost certainly a scam. GAW appears to be running quite the Ponzi scheme.
I fully agree.
They already scammed with Hashlets, and I'm sure they will scam with HashStakers too.
Hashlets:
They claim they are mining, but they are not mining, So the fees to cover "electricity and repair" are the scam. The proof they are not hashing is the bitcoin blockchain (or another cryptocurrency blockchain). They never could show in the blockchain they are hashing, usually they send a picture of a mining farm, haha!
They promised Hashlets will ever be profitable, but last week they made negative payouts. Also, the value of hashlets are dropping in the market, because people are realizing that payments are decreasing and never will have the money back.
HashStakers:
They are using the name Paycoin, but Paycoin already exist. Based on "Gnome" case (Gnome Foundation vs Groupon) there is a high risk of legal problems, because no matter it is not registered trademark, "Paycoin" is a pre-existent "Art" for the law.
With Hashlets and Hashstakers, it is evident that they are borrowing capital from their customers invoking cryptocurrencies to seduce cryptocoin community, but there is nothing related with cryptocurrencies here. They are not mining, and the coin they use to stake is not descentralized, does not have a public trackable blockchain, and you cannot have your own wallet.
