Too much presale discounts will be bad for main sale investors.
Look at the other projects. In many of them it worked like that, and it worked good!!
What are you talking about? In which cases presale discounts have worked good for main sale investors?
I know of none, honestly. Doesn't matter really, hodl the coins you have and buy the dips when they come, no doubt in my mind datum will drop at least 40% after the listing but that'll be a great place to buy, I can easily see this coin reach 1$ in 1 year
It depends on your investment horizon. If you flip every ICO, sure, discounts are bad, but if you are in in for the long run the initial dip doesn't matter.
