answer:That paper is a little hard to read because of grammar and structure issues. It does not describe how Bitcoin currency is created, nor how the value is determined. It also does not describe the interaction between existing currencies and Bitcoin. Bitcoin can’t replace currency completely because real goods and wages are paid in currency, not in Bitcoin. So as a marker of relative value for online transactions, Bitcoin is intriguing as a way to avoid friction in foreign exchange. It can be taxed when one converts it to a real currency or a real good. But there seems to be no control over the growth of the money supply, which means a participant is at risk of losing all overnight with no way to predict instantaneous inflation or deflation. And being ex-government, there is no recourse for criminal behavior. Why counter them? There is no case for saying they should not be allowed.
