I find I strongly agree with your assessment of BTC. As the big money seeks safe havens, in this prehyperinflationary environment, BTC is having it's heyday.

Statements by heavy hitters in fractional reserve banking indicate that cryptocurrency will replace fiat, but those players aren't interested in games they don't completely control. If BTC won't be just as useful to them as fiat, they will make alts that will be, and this is just the way of the world.

In my final analysis, I don't think any one coin will become a new 'dollar' and dominate the currency markets. Rather, like conveyances today, a diverse ecosystem of blockchain based currencies will fill the various needs of users, although the ephemeral nature of code will enable practically unlimited variety to arise and execute myriad purposes.

It is through the practical uses of blockchain in infinite expressions that both security from plunder, and the dominance of coercive - and corrosive - substantial holdings, will simply replace any particular currency, including BTC.
