With only faucet (whitout ref for every faucet) is very hard earn 1 milion of datoshi, but not impossible, depend of many hour you dedicate to this work (have more faucet with low rewards, but claim every low minute) and how many captcha you get add first to get crazy
Lets just face it, its impossible whats he asking for lol.
Nothing is "free" hence if it doesnt cost you, it`ll cost you something else which people dont consider is "time". How much "time" would it take..
