When it comes to PACMICz, I consider it a loan to BitMain/Hashnest, which I quickly get back with a decent interest rate. With the paid back load + interest I can re-invest it anyway I want. At the end, we as customers get the option to invest in S6s.
Win-win.
Where can you invest on S6 on Hashnest? I can only find S5
S6 is not on sale yet, expected late Summer.
