I am not talking about the private sales and pre-sales. I am talking about the main sales.
Don't you think ICOs should allow people to invest any amount of money they want? It will cause the tokens to be distributed among more people.
Assume that 1000 people are participating in an ICO and each of them is investing only 1 dollar. Don't you think they are more helpful than a person who is investing 1000 dollar?
Better to consider a maximum amount instead of a minimum and do not let the whales manipulate the price.
It is just their decision to easy count the investors and avoid also a very low capping and fund that they will going to get. I think it is a good decision in order to collect much better fund rather than to let investors spend too low.
