Bitcoin now not only seems to be firmly in the hands of Communist China, but may be a major contributor to the ongoing global semiconductor shortage and the unprecedented crises many power grids all over the world face.
Even if you don't understand cypto-currency, this article describes "mining" in layman's terms; and then ties mining into the power-grid shortages.
It also sheds some light on why China is interested in Gibraltar 
which is heavily involved in FinTech.
Read the whole article to find out just how much China owns.
Excerpts -
The (computing power) increase in difficulty means the amount of coins each miner generates decreases, which is what has ultimately led to the long running cryptocurrency mining arms race.
Regardless of how much hashpower each data center can create, finding blocks is still mathematically random and is subject to statistical variance. Because of this, miners form “mining pools,” which are effectively cartels of different data centers...
The top five mining pools in the last year of data are F2Pool, Poolin, BTC/com, AntPool, and Huobi Pool (Huobi is a Chinese-founded cryptocurrency exchange**, AntPool and F2Pool’s All Rights Reserved links to the same gov/cn domain).
Also, the top 12 are also Chinese-connected and comprise an additional 24 percent of all blocks found in the last year.
Because the Bitcoin data centers run 24/7, not to process transactions, but to calculate SHA256 for a chance to win the next block’s lottery, each 3250 watt miner will consume roughly 28,500 kilowatt-hours per year.
In January, CCP-ally Iran suffered rolling power grid failures, which left the capital city Tehran crippled... officials say the culprit was more than 1,600 Bitcoin mining facilities, some legal and others underground, which had overloaded the country’s electric grid capacity.
In November of 2020, RadioFreeEurope reported the Georgian state of Abkhazia suffered the same fate as Iran after Russian mining operations moved in to take advantage of cheap electricity, overloading the country’s grid.
Given Gibraltar's interest in FinTech, having an updated power station might have been more essential than realized.
