I wanted transaction alerts on my wallet addresses without having to import the private keys to a web wallet service, so I made this: https://wallethq.com/ - the main idea was to get peace of mind my cold storage hadn't been hacked, rather than compulsively checking it every night.<p>But with all the speculation about what will happen to bitcoin values when the FBI offload 144K BTC from 1FfmbHfnpaZjKFvyi1okTjJJusN455paPH, I thought it would also be useful to share WalletHQ with you all, if you wanted to receive an alert as soon as it moves :)<p>Please let me know if you find it useful!
