I have a peculiar question about this 400UNI giveaway - what if one person was using several wallets and made some transactions on uniswap with each one of them, will this person receive 400UNI per each wallet?
If so - that is ridiculous
Yes, 400 UNI can be requested for each wallet that participated in trading on Uniswap. One message above from your post
https://bitcointalk.org/index.php?topic=5276386.msg55216593#msg55216593, xOdiumNostrumx writes exactly this, that it received 800 UNI for using 2 wallets. I have met such lucky people who received 400 UNI for dozens of their wallets.
