yup only way to avoid it is to send me all ur coins!
While you probably meant that in jest, it actually IS how you avoid Demurrage, loan your coins to someone else at 0%, the borrower pays the demurrage then returns your coins 1 for 1. You've just successfully avoided paying demurrage. Now of course the borrowed coins in the borrowers hand are undergoing demurrage too so they need to come up with more coins then they initially borrowed (just like any loan), maybe they invest, maybe they sell their TV, you the lender don't really care so long as you get your coins back. This is what we want to see happen.
