Why is a minimum purchase introduced?
Min. Purchase :
0.0074 BTC
0.385 ETH
50 USDT
I think that this is a condition of the exchange in order to minimize the load on the power of the exchange itself
It makes no sense to buy tokens for less than 50 USDT.
Even taking into account the growth of the price by 100%, you will not get tangible profits
Investors are people who want to support the project, believe in the idea and want to make money. Therefore, the minimum amount of investment eliminates spam transactions
