I think this is cool and all, but... It is not really needed. I can send a tip now to anyone displaying an address.
The benefit of changetip is that you can tip people who don't have an address and therefore bring in new converts.
I guess I did not understand. That is kinda neat. But who holds the coins?
That's my problem with changetip as they hold the coins for 7 days and than return them if the tip is unclaimed . Additionally , they will soon be charging a 1% fee for withdrawing BTC thus encouraging large amount of users to store a small amount of coins with them for tipping.
It would be great if someone would create a off the chain tip bot that was decentralized and free to address these concerns.
They do deserve to be rewarded for their efforts though in the interim.
