Good news for $DYDX holders!
Skel is also cooking a new-user transfer. Let's hope it will be juicy. 👨🍳
I won't say that. People had to fill out the Google form in order to be eligible for the rain drop. I am not sure if anyone already created a bot within a few hours to fill those forms with random information. It's not like bots have to submit the same information in all the forms. The accounts must be unique to get rain drops. Also, I want to believe Metawin has a strong system to detect multiple accounts. Even if someone manage to get rain drop in multiple accounts, I don't think they will be able to get away with that.
Bot/alt abusers are pretty common in crypto space. Of course, like every other platforms, I do think metawin has employed a way to comb out abusers as well. Actually, during the rain form submission, Skel mentioned the bots have verified emails lol thus it's safe to say they have been targeted.
However, I do not think there exist an impenetrable wall for this. The usual will happen, some will get away, some will not. The rain was also in our web3 wallet, as much as Iove the zero friction that comes with it, it can be a double edged sword at times like this. But at the end of the day, such things are nothing uncommon in the crypto space.
I just can try to all-in win 1x time withdraw and losses doesn't matter cause getting the money back.
