The impression is too excessive, whatever is offered may not necessarily come true.
for me personally would not dare to participate in an event like that.
by the way does anyone know what exactly they have to offer?
This is a degen play. Means the project is over hype during their sale. 170eth will be easy filled with the kind of project related to a polkastarter project that made 25x during their sale.
If this guy got in during the spider dao gas war, he already multiplied his 0.8eth to 4 to 6x. These traders doesn't necessary need the service or product of the project cause they will exit with a profit. After that jump to another ship. That's how hype on a degen play. Its up to you if you don't want but the profits earned here doesn't take more than a day to get. Its a high risk high reward style.
