Yes 5.100 ETH is already a great amount and the ICO is running for 6 more days. I am sure a lot more people will contribute.
Actually i think it's very low for a project like vibehub. It makes vibehub incredibly under valued.
There is a new tech that we all know in three years it will be every house.
And vibehub is the best content on this tech for now. And development already finished!
Yes 5.100 eth is a good amount of money but for vibehub, it's just a indicator of its under value.
Good time to invest, hard to find Ico's that are undervalued. And being first with a good product in a competitive field is very important!
