Just to start this off right. I am a beginner java level coder. Learned a little awhile back and recently picked up learning again, Teaching myself.

I decided for fun i would make a donate button for my favorite crypto currency.

I am editing an open source code found here - https://github.com/scottycc/coinwidget.com

And am stuck on this. When you click the send donation button it would normally open the users bitcoin wallet. well in this case i want to change it to my crypto currency of choice. Stuck on where to edit that. The images and everything i wanted i already have inserted.
