But as it is fucking hard! (besides vanitigen not working full-length address)

I have already seen another all upper case vanitygen address in a sig on this forum so I think this must not be correct (at least with the current version).

That's my address

The problem is not length, it's how specific of an address you are looking for. There are about 58³³ possible address, so if you want to find a very specific one (such as 1BitcoinEaterAddressDontSend..), then you have a 1/58³³ chance of finding it on each guess (infeasible*). However, my address was not a search for a single address, it was any address of all capital letters. There are about 26³³ such addresses. So the chances of finding one such address on each guess is 26³³/58³³ = (26/58)³³. That is actually in the realm of feasibility -- it is about 1/300billion

* 1/58³³ = 1/15599970876632771988160814054146447252125923204784443097088

why 58 ?
i think it's 62, 26 * 2 + 10 = 62
