Wow, the airdrop received 3 years ago is 280 U!
DeGate is the ZK Rollup order book DEX made by Gulu (the founder of Bihu, which is well known to all old leeks). Two days ago, it finally opened DG applications, as long as it meets the standards in the social media issuance in 2021 (has been issued before 2021 Encrypt related posts) and participate in the lottery draw, you can go to your own address (https://degate.com/socialNetworkOffering), and the minimum guarantee for a single number is 500 DG.
I had 3 social accounts at the time (two Twitter, 1 Weibo) that met the standards, and received 500, 500, and 1,500 coins respectively, for a total of 2,500 coins. The application fee was uniformly 80 DG, so I received a total of 2,260 DG. Based on the current unit price of 0.129 U, it is about 280 U.
However, the cross-chain handling fee for withdrawing to the exchange is about 30 U.S. dollars, so the actual amount you get is 250 U. However, after all, it was so long ago that some friends may have forgotten which address was registered at that time. I even saw some people misunderstanding it. I deleted the old address....
This also gave us a little experience. Any address that has interacted with airdrops or has rich traces on the chain must be backed up (I usually use two devices + paper). You can also buy a hardware wallet and open a few more wallets. Make a note of the address (OneKey + Little Fox is very useful), so that unnecessary losses can be avoided if similar situations occur later.
