imagine if the price of one coin is quite high, but we are paid in dollars, then what is the function of the price of the coin being expensive?
It doesn't have function. It will not give the different because you will be paid equally with the total amounts of dollars that already promised by the developers. The developers will be distributing equally with how much dollars that got by all of campaign members. That's why there are some members prefer to be paid in amounts of token instead of use the dollar as a way to determined total allocation as it will be more profitable when the price will be mooning.
you have to differentiate between dollars and usdt, and you have to know that american banks don't recognize that usdt is a dollar, this problem has existed since the birth of Usdt, but usdt is a stable coin that was created.
There's no need to differentiate between dollar and USDT as USDT backed by dollar to make it as stable currency. Forget american bank coz they will recognize USDT later as stable coin. Total pool allocated in dollar = total pool allocated in USDT. Dollar = USDT. I should remind you this if USDT = USD token.
