Sorry, who wants 300% ROI in a month? It's never been mentioned on this board and is a dishonest form of argumentation.
Critics of the IPO have been confounded by the fact that Galfry is asking for 100% of the capital required for the project and yet only offering 20 % of the equity. It's an extremely poor ratio (especially since the business is a start-up with no track record) that undermines any investors ability to achieve the potential "upside of the venture".
The other main criticism is the business plan itself which seems to be wildly optimistic and, as Galfry himself admitted, is no longer accurate or representative of the business.
The "trolls" have taken the time to read the prospectus, analyze it and inform the community about the nature of the business venture in a comprehensive and reasoned manner.
Actually, public investors will start with 40% equity until their initial investments have been paid of. That seems quite fair.
Of course it's risky like all bitcoin-related investment and it might always remain niche, but if it achieves visibility, which by the sleek look of the website, the usefulness of the service and the dedication of the founder I think it will, it could become quite lucrative.
