Few days ago I've realised that cryptocurrencies might be the "easy thing", the button that pays some money to authors that Stallman always gives as solution to sharing and compensation in his talks. Cryptocurrencies are pure software. As such they do not have additional costs and are easy to implement an integration for payment. Don't know why I haven't seen it until now. Might be the acceptance that cryptocurrencies are receiving lately that made me realise it.
