I've never had much luck with auto-betting, especially on freebitco.in. their house edge is way too high. as soon as you claim, you are asked if you want to multiply your bitcoin. the vast majority of people who gamble on that site will lose, thus replenishing the faucet. it's a great faucet, as long as you're not greedy.
So that means you can't used automatic bot here, instead of using automatic bot may be you can stick to manual bet which is more safer. You need to target on how much you are going to earn each day. I believe this is not that hard to earn. Like for me usually just make an 0.001-0.003 btc target for each day. Although it is not much but I will slowly get my coin here
