I agree, in general, they are a waste of time. But if you are starting in the world of cryptocurrencies and you need to give a boost to what you are doing there are some faucets that can help you do it. Personally, coinpot and freedodge has allowed me to do enough to buy some steem and ether for Lunyr. If you do not have to mine at home or capital to start the faucets are an alternative. 😄
