Re: What would you do if you generated a Bitcoin address which had 100btc in it.
After reading this topic, I am going to generate 1million address a day... 
lol, I was thinking about making software to to do this. Generate address and see if one address has any balance
This has already been done. Read this thread:

You can download the program and start searching.
You will never find one but if attempting impossible things is something you like to do, have at it.
Incorrect!
It is certainly possible to run that program and guess a correct key to gain Bitcoins.
Its infeasible sure, the likelihood of this working approaches the impossible but never ever touches it.
Impossible is defined as never able to be done under any circumstance.
Just because the key space is large and searching it may take a trillion trillion years does not make the task impossible.
Also do not forget that even if you find a valid address, chances are much more than 99.99 % certain it is a wallet with no coins (generated by another vanitygen).
That's a small chance. But,, it can still happen..which kind of scares me.
If you're scared of this, then you sure as hell should stop using banks and credit cards.Because the chance of someone guessing your credit card details, AND your online banking credentials (AND winning the Powerball twice in a row) is still much, MUCH larger than someone accidentally generating your bitcoin address.
Or getting struck by a lightning...twice in a row.
There has been at least one person that got hit by lightning a half dozen times. The truth is the odds against address collision are so great we cannot comprehend the vastness. We don't have any way to grasp it.
