I'm not sure which one wins, but here's 3 bitcoins
not sure why each exists, but here's my best guess.
there's bitcoin 1mb, (too slow for retail establishmets)
then 8mb (visa speed, and you need visa talent to transact these),
then bitcoin 2mb, the paypal transaction speed---
so 3 bitcoins---1mb to get you in,
one for retailers, (2mb)
and one for credit cards---(visa speed, 8mb)
