starting a faucet is not good idea right now. as other member said you may need 5+5BTC investment , you can invest 10BTC in another good project and earn good money, much more profit then running a faucet
Honestly I don't have much Bitcoin for sure but the answers on the topic seems little bit unbalanced , some people are saying that I should need like 10-100$ tops but the first answer says 10 BTC
It's not even close .
I'am willing to use paid domain , .com which is better for SEO and I'am not really planning to use FaucetBox or any simillar website that use a third party , I want something that pays directly to the user adress and honestly didn' tfind any Open source for that , something like Freebitco.in should do the job and I'am not sure how it would cost to hire a developper to do that job .
