FreeBlock @IiiisShack

Blur0撸A7的技术向复盘 先说战绩：blur从12月底开始操作期间尝试了七八种策略，3阶段到手了9万多分，分布在差不多20个地址里。其中大部分成本为0，甚至在获得积分的基础上小有盈利，答应Freeblock的群友进行一下复盘总结，希望能给大家以后参与项目带来一些灵感。

Twitter user FreeBlock shared his experience of earning millions by participating in the third round of Blur’s airdrop program through various bidding strategies in a scientific manner.

The specific bid strategies are as follows:

1、 By monitoring the memory pool, if there is an offer transaction that accepts his bid, he will use higher gas fees to withdraw the bid account balance, causing the transaction to fail (high feasibility);

2、 With the restriction that NFTs cannot be traded within 3 hours of going live on Blur, bids can be confidently placed (not a key strategy);

3、 When gas fees are high, users tend to not accept bids (low profits and give up);

4、 Cross-platform offer-bid price difference arbitrage suffered a huge loss when forced to accept bids due to robot manipulation (price was manipulated by bots);

5、 Changed the expiration time of the bid from the default permanent to 10–30 minutes;

6、Bidding on some NFTs that could not be bid on by bypassing Blur’s restrictions (which was later fixed).
