B3 is just B3, (B – from Bitcoin fork, and 3 is just super powerful number ), If you want to give a meaning to 3, maybe try the fundamental equation of energy, mass and light, or try various religious significance of number 3, or if you prefer, try 3 from Chinese numerology, meaning a Star, which B3 is likely to become. I am not sure where you have obtained B1, B2 or B4 from, perhaps you could enlighten me. ‘Smell of money’ as more like a fiat talk and not of much credence given by honest cryptospherian coins such as  B3 which are building  equitable infrastructure for humanity, which fiat started but lost in way or was hijacked by less enlightened ones,  and now has the undesirable  effect of stressing both humanity and our precious planet with its precious cargo hurtling through space.
