Wallet from blockchain.info change the receiving address from time to time. I guess the rationale is to protect my privacy or something.
In reality I'd be more secure in my head if I had the same BTC address...
Solution to that would be to create own vanity address, but in the meanwhile - is it OK if I publish the address on the website and will it work in 6 months?
EDIT / UPDATE: Wish the changing addresses were better explained - https://en.bitcoin.it/wiki/Deterministic_wallet - I was quite seriously worried why my address is changing.
