I assume it was a typo but why cant they acquire Real Estate Worth 6 Million? And it is obvious that no ICO will raise 6 bln.... I think that Vitaliks advise fits to every ico that invests. If you develop an App you do Need more than a hardcap but for Investments ? Sky is the Limit !
No, it wasn't a typo. Transaction volume in Berlin is around 6 billion per year. See the 3Q17 report from Colliers:
http://www.colliers.com/-/media/files/emea/germany/berlin_research/office-letting-investment-berlin-infographics-colliers-q3-2017-en.pdf?la=en-GBThat's why I said that even if they could raise that much (which they couldn't), it would also be impossible for them to invest it. So they should set a reasonable cap based on the max they think they could actually invest over a certain period of time.
My guess is that they are probably capable of investing more than they'll actually raise, but a cap helps with the optics of not being "unlimited". Just set it to a number that's reasonable based on their resources as an investor.
From an operational perspective, it shouldn't have an impact, but it could help raise money.
