I think it will be cool if the minimum purchase can be reduced to 50$ in ETH for many people to buy. At least they will be able to top it when they have more funds.
Umm, to be honest, I think $50 is a bit low for a minimum investment at this stage of the ICO, they are offering a 24% bonus, and this should only be available to larger investors. I think they will reduce the minimum investment when the ICO gets to a later stage and a lower bonus %.
