There are two ways to participate: Method 1: Choose the free miner "POTATO MINER", and you can mine after casting, and you can dig and sell it while digging (civilian version); Method 2: Choose a senior miner (there are multiple choice combinations). You may need to upgrade the room according to the situation, satisfying the room energy ≥ the sum of the mining machine energy, and the mining speed is faster (Krypton Gold Edition). Some experiences: Early participation benefits early, and late participation may have a high probability of collapse. It is not recommended that novices buy miners directly, because reasons: 1. There is insufficient space and the room is not upgraded. You can only put down 3 senior miners at most; 2. The upgrade cost is expensive, the BIG price is high, the return cycle is short, and the risk is high. There is currently no limit on the number of accounts, so you can conduct multiple mining. In addition, the ideal combination of krypton gold: 1 senior miner + 1 free miner. Advocate the "poaching and selling" strategy to prevent the risk of collapse. The following are screenshots of the returns of different combinations for reference (the following is the historical data on April 9) 1 free miner 1 free miner + 1 senior miner (20 BIG) 2 senior miners (20 BIG)
