Does DannyHamilton have a tip jar?

No, because I prefer to use a separate address for every transaction. I don't like to re-use addresses (which is required in the case of a tip jar). If anyone ever feels an overwhelming desire to tip me, they typically PM me and request an address to send the tip to.

If anyone has ever sent me a tip they should never re-use that same address to re-tip me in the future. It is necessary to get a new tip address every time. I frequently discard old private keys and addresses after I've used them, so unless you check the blockchain and verify that there are still currently unspent outputs at the address, tips sent to an address that I've used before will likely end up in the great bitbucket in the sky never to be spent by anybody again.

Why dont you just use 1 address?

Using a new address for every transaction increases anonymity and more importantly security. It is the way that Bitcoin was intended to be used (though for simplicity and to avoid confusion for those who don't understand how bitcoin works, several of the lightweight wallets unfortunately encourage re-use of addresses).

If you read the original Satoshi Whitepaper you'll find that in the second paragraph of section 10 it states:

a new key pair should be used for each transaction

Ok, thanks for the great information!
