The longer the POW, the more valuable, and the longer the POS, the more junk. POW is a fair competition model similar to the Chinese children's college entrance examination, will not give a child because he has money and give him points, and POS is that the family has money can add points, POW or POS, rich people refer to the currency standard, not the RMB standard. Do you think Bitcoin is a casual success? Without a fair mechanism, how can there be a constant change of dynasties? POW represents the Bitcoin dynasty countless times, and POS represents the same dynasty as the Bitcoin dynasty. Pure POW currency is very scarce, BTC, LTC, IFC, DOGE as the representative, and the total amount of pure POW is only represented by BTC, LTC, IFC, in which IFC has greater potential, opportunities for discerning investors, hope that strategic investors to join, inject technology, inject resources, because IFC is an open source project is not a stock.
