You have to post then wait 4 hours. Also, I'm not sure, but there might be some requirement about how long/meaningful that one post is. Not sure about that though.

It has to be 4 hours since your first post, I think.

Hello and welcome! I suggest you read https://bitcointalk.org/index.php?topic=177133.0

It was exactly that site I used, but I hit their CPU limit after ~500 visitors.

My current site goes down after about 500 daily visitors. I used too much of the CPU. The site itself is very small and all the images are hosted on another server. So 5 GB bandwidth/month should be enough. The functions I need support for is PHP, MySQL and fsockopen. Also, it has to accept Bitcoin if it's not free.

Welcome! I suggest all you new guys read https://bitcointalk.org/index.php?topic=177133.0 and http://free-btc.net.tf/#!/whats_btc (the latter is currently down, but should be up again once the DNS updates)

I have created my own faucet. The problem is that I have too many visitors for the free hosting I am currently using, which results in a lot of downtime. Is there any hosting that's either free or costs at most 5 mBTC/month and that can handle many visitors?

As long as you make more money than you pay in electricity I'd say you make a profit. Of course though, you also need to reach minimum payout. So maybe 250-500 MHash/s?

Welcome! I hope you'll enjoy your time here.

No, you can't see that AFAIK at least.

Before investing in bitcoins I suggest you go back to school.

Probably people would split up their money over more addresses, I guess.

I think someone on Reddit did the maths, and it is practically impossible to crack someone's keys with current hardware (unless you maybe have access to one of the best computers in the world). I don't even think a large bot net would be enough.
