EHC digital currency

1. You have to remember that in addition to bitcoin, the remaining 99 digital currencies are packaged to circle money! 99% of digital currencies have no value. Ecosys TEM health chain (EHC) is a decentralized big health ecosystem established by using blockchain technology, artificial intelligence and big data. EHC integrates medical big data, connects online and offline medical data transmission, and records data to the blockchain. EHC also supports three-party developers to deploy DAPP based on EHC, and to call the data on the chain
but! Now these projects don't work? It's all packaged air. What's the practical effect of blowing so high?

2. It's better to excavate in the 12th floor, not because there are most minerals, but because it's easy to brush magma down the 11th floor, so it's better to excavate in the 12th floor.
the well method is to excavate vertically, with two sides of 1x2, so that you won't fall into a dangerous place just because you only dig at your feet. Then you can put a ladder in one passage and water in the other end, so you can jump down when you come down, Save time and don't die
the fishbone method is to first dig a main mine on the 12th floor, and then dig branch mines on both sides of the main mine, with 2 blocks in the middle of each branch mine, so as to maximize the mining efficiency

3. That's what I do. It's very good
