Correct Mike, the SDR is the IMF's doing. This past year saw the inclusion of the Chinese yuan in the SDR, showing just how influential China is.

I suspect that the digital ledger tech supporting today's cryptos will be implemented by central banks/national governments and backed by the SDR in the not too distant future. They will likely enact this one world currency after a sovereign debt crisis, bond market collapse, or equity sell off. This will leave them with the ability to keep their system running should fiat lose its luster.

That is not to say that today's crypto cannot continue its price surge in the coming year. I am positioning for a "melt up" in cryptocurrencies. However, once the business cycle takes a turn (and more importantly, global debts come due & central banks are illiquid) who knows what will happen. Historically, the most speculative assets sell off the hardest during any contractionary event, and it's pretty clear that speculative money is flooding into crypto. So it stands to reason crypto will be correlated to the overall market should a major recession occur (however, I go back and forth on this correlation).

Longer term, it seems inevitable that the IMF and central banks will collude to make sure their portion of the pie stays fully intact, if not larger due to the complete transparency crypto offers. This is just my two cents, folks. The more people learn about these things (rather than just looking to get rich) the better chance crypto has of improving the system.
