I have read your post in detail and I find it interesting to contribute, that if bitcoin and ethereum remain solid, they should also invest in appropriate technology that allows them to process a greater number of operations per minute. Or maybe they favor the system to be slow? In another order of ideas, related to the topics that you cover in the publication, I have read some info about an organization called FATF, which is exercising actions in certain countries trying to intervene mining generated by bitcoin, which is known , which serves as covert support for terrorism and drug trafficking. As well as certain bitcoin machine owners to do mining outside the law by obtaining money laundering and without any legal support.
Well, friend, I hope you liked my opinion,
