I had overlooked this as well, can't invest as much to obtain the 47B Platinum Creditcard unfortunately, thought I am in anticipation for the classic one!
Its a nice opportunity to get the platinum credit card. But unfortunately 5 ETH investment is way too high for me also. So I cannot get that. However FSBT token itself is having lots of potential. So I will HODL my investment in FSBT for sure.
If forty seven bank ICO can reach their goals and proves to be a viable and beneficial platform, I am pretty sure I could upgrade to a platinum level by storing my funds there
