Some thought on the ROI for this ICO. I participated in the pre-ico so it's a little different story but for those thinking of participating, it might not be very profitable.

Since ICO is until end of Feb and they have heavy marketing, it's almost certain it will reach the hard cap.

Total Funds Raised = Pre-ico + ICO = 2,500,000,000*0.01 + 1,000,000,000(0.017+0.018+0.019+0.02+0.021+0.022+0.023) + 500,000,000*0.024 = 155,000,000 EUR = 182,674,475 USD (today's rate)

Assuming my calculation is correct, it means right after the ICO, 1 BNK = 182,674,475 USD/(2,500,000,000 BNK + 7,500,000,000 BNK) = 0.01827 USD or 0.02 EUR, so people investing after 0.02 EUR, so from 4,000,000,000+ BNK during the ICO is losing from the start.

Then, now to think about market cap, it is certainly not easy to reach 182,674,475 USD in market cap, since it will land BNK to about 30th in cmc. Although in the long term I think it is attainable, and even if after Banker immediately reach this valuation, the profit is not great.

When say BNK reach 400,000,000 USD in market cap, basically doubled, 1 BNK = 400,000,000 USD/10,000,000,000 BNK = 0.04 USD
This means even the early investors who bough BNK at 0.017EUR = 0.02USD would only have doubled but those at 0.023EUR = 0.03USD would have 33.3% gain.
If you participate late, not amazing at all.

So I guess my point is either you invest early or you don't invest at all and look for other ICOs to invest.
