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.
The whales investors in the private sales and pre-sales are having more limit to invest on the project, because they have lock period usually.
But in ICO, almost there is no lock period, therefore ICO limiting the amount of personal cap in main sale.
Otherwise, the main sale investors can manipulate the price of the token/coin.
