B3 is pure POS coin from inception. Bitcoin was a ground breaking invention to deal with runaway fiat inflation ( inflation is a direct result of removal of gold standard, so any amount of fiat tokens could be created at will, and relative values given by few select first world countries peer reviewing each other at the expense of other poorer countries whose fiat values become worthless for parity purchase acting as modern slaves to product goods and services for them )  but unfortunately Bitcoin POW is its fundamental flow in this evolution. POW which is rapidly sucking away global energy resources, and it will soon utilize more energy than Japan (currently Bitcoin network consumes more energy than Nigeria, country with around 200m population). The issue of planetary ethics and environmental degradation arises. Unless unlimited clean energy is found soon, POW bitcoin and other POW coins are likely to bring planet to its environmental breaking point. Ether has seen the light is attempting to change to POS.
Coins like B3, with pure POS from its inception has unprecedent advantage  (similar to bitcoin at inception with POW). B3 has arrived on the scene without much fanfare (again similar to bitcoin) and most likely shape the future of cryptosphere, as with minimal energy consumption, much higher security and faster transactions with greater anon, is most likely to win the hearts and minds of people and lead to mass adaption. Lets just hope B3 has enough circulating supply as too much scarcity leads to higher fees and ultimately vast majority of humanity which survive on few dollars a day can no longer participate , impacting mass adaption by individuals every country and further impacting wallet /node decentralization. Supply of trillion may be a good staring point for participation by every individual on the planet including 2B living under 1 dollar per day if B3 is serious about bringing honesty, integrity and fairness to all humanity.
