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.
You have a point there, but the major reason in my opinion concerning why ICOs set a minimum amount users can buy is mostly because they have put a price tag to the value of their project. They feel their project aint worth $10 investment and feel its an insult for people or participants of the ICO to buy $10 worth of their tokens.
