Bitcoin faucets are like free food. People will do anything for "free" food.
the difference is that in the second you can use a bot and increase your profit and also you can earn bitcoin directly without buying them, and in the case bitcoin go up(like now) your earning will increase drastically
also faucets is another way of earning money in a more anon way
