I recently browsed some test networks and found that Goerli's test coins were the most difficult to obtain. I often encountered the situation where the faucet had no water. Later, a big guy helped me solve the problem.
First, the most commonly used one is: https://faucet.goerli.mudit.blog/. You need to post a tweet and use the Twitter link to get water. The advantage is that you can get a few more ETH at a time, which can be used for a long time. The disadvantage is that there is often no water!
The second one: https://goerli-faucet.slock.it/. You can receive 0.05ETH at a time. The advantage is that the operation is simple. You only need to enter the wallet address and confirm it. The disadvantage is the same. There is no water to receive at a time.
The third one is the most useful so far: https://goerli-faucet.pk910.de/ This is a mining webpage. When you need goerli test coins, enter the wallet address. You can mine online without linking the wallet, as long as the page is not closed. According to my test, the mining speed is sometimes fast and sometimes slow. When it is fast, it can mine a few ETH in 2 minutes, and when it is slow, it may take more than 10 minutes to mine a few ETH. However, it is completely sufficient for emergency use. It is a must-have medicine for home travel and hair testing!
