Proof-of-work coins such as Bitcoin, Monero, and Zcash will lose all their security in the coming crisis, because miners won't be able to exchange BTC for fiat to pay their electricity.
I was looking at the last 6 Months of the US Dollar Index, and I Totally Agree with You ,

The US $ is Going Up,
The Best Investment at the Current Time is the US$ , not PoW Cryptos or Metals which will all collapse in price against a Strong Dollar.
Soon the Smart money players will dump everything for the US$, Charts are already starting to show it.
