Bitcoin alert service if price dips or rises by a percentage base? Is there a Bitcoin alert service that monitors the price and alerts the user when price dips or rises by a percentage base? Say I want to monitor the btc price if it rises by 5% and have it email me.
I have never used it personally, but I have a lot of good things of the Bitcoin Paranoid app. It's supposed to alert you on price changes.
