Community Hot Topics

friend.tech's experience in rushing and getting numbers

1. The project developer uses smart contracts on the base to monitor new users and fan counts, and starts buying operations when the conditions are met, but there may also be condition errors, so caution is needed.
2. Someone mentioned the method of grabbing money on the base, including obtaining the addresses of influencers and waiting for them to deposit, and then continuously making purchases. This strategy is considered effective.
3. The discussion involves comparing different crypto projects, including FTRoom, BSC simulation trading, and their respective experiences and profits.
4. The discussion also mentioned the method of using AI to batch create accounts, and some users shared their profit situations, including earnings of 0.1u and 0.5u. In addition, someone is concerned about whether the shareholding will only increase and not decrease.
5. Someone mentioned that a user's key may have rug risk, so caution is needed. At the same time, some users mentioned that the bot they use only makes purchases.

Discussion on alternative proxy tools

1. In the discussion, someone asked if they are using software routers and mentioned that they are using OpenClash. Another person answered affirmatively and said they are using OpenClash, but encountered some problems.
2. Another person said that they have fully adopted Surge and believe it is more worry-free. Someone asked if Surge can be installed on a software router and suggested buying a Mac Mini M2 as a software router and using the Surge client on Mac. However, someone also mentioned that their Mac is facing performance issues and a series of configuration problems.
3. Someone plans to buy a Mac Mini M2 on Pinduoduo to use as a router.

Requesting and storing transaction data in the tens of millions

1. In the discussion, someone mentioned dealing with transaction data in the tens of millions and asked whether to use MySQL or a big data database (such as ClickHouse) for storage. Someone suggested using ClickHouse.
2. The discussion involved storing balance data of USDT and WETH liquidity pools and mentioned having 9 million data on-chain. They want to store the data locally to improve query efficiency without relying on APIs.
3. Someone mentioned that querying prices using APIs is not sufficient and needs to find the price of a specific block number. Other members suggested using RPC service providers to obtain balance data of block numbers and addresses, with Ankr mentioned as a free option.
4. The discussion involved analyzing historical trading data of tokens, needing to calculate the buying and selling prices at that time, and how to obtain the price of a specific block number. It is recommended to use Ankr's archival node to obtain the required data.
