1 - In BTC's life, governmental, institutional and the general public's perception of BTC , has gone from the untrusted and unknown to the trusted and known. Do not under estimate this trust - See next point.
2 - BTC has already made it as the only globally trusted and used digital currency, it is: "The King." BTC is being used for the following reasons all of which are growing rapidly within their own field:
a) On line commerce,
b) As a store of wealth,
c) As an investment vehicle,
d) Is being legislated for,
e) Physical outreach is limitless.
3 - No competition. Considering points 1 & 2 above and the fact they are all growing exponentially, no new coin can replace BTC . Would you trust a new coin? And even if there is a new coin, it will only be a fork of BTC so either way BTC has already made it, even astronauts have heard of BTC! ;-)
4 - Is finite in , is immutable and can not be created, hidden or destroyed and everyone can if they wish see exactly where every single Satoshi is at any one time. So
A fantastic flag of victory for BTC . I've heard values for BTC as high as $400,000...
