I agree with you on NXT being superior, but the decimal argument just does not hold ground. It's just decimals, the comma can be moved etc. That cheese burger cost roughly 2,43 mBTC.
The Bitcoin price and decimals is a real problem. It's been 4 years we are talking about it but nothing has been done to solve the problem.
