Back before 15th February 1971, the UK used pounds, shillings, and pence which were abbreviated to "LSD".
The coins were the half-crown (two shillings and sixpence), shilling (12 pennies, also known as a "Bob"), sixpence (6 pennies, also known as a "tanner"), threepence (or thee pennies, also known as a "thruppenny bit"), one penny (or 1D), and halfpenny.
So "D" was "PENNY" and UK crosswords still use it.

Insana: The pied pipers of cryptocurrency are leading investors to their doom
In other news, U.S. Feds eye crypto-currency; think it might be used to "evade taxes" (!) and are implementing counter-measures (firms required to report ANY financial transaction over $10,000).

That's just too good, a CNBC shill calling out cryptocurrency shills! 
US banks already have to report transactions over $10,000, so having crypto exchanges do it is just more of the same. I'm surprised it wasn't the case already. They're already subject to the same KYC (Know Your Customer) rules if they allow cryptos to be converted to paper.

What I find amusing, after the various defenses of bitcoin, that it last nearly 1/3 of its value in a couple of weeks.
Does anyone else hear a loud flushing sound?

The volatility indicates that it's not ready for prime time. But it's had big corrections before[^], only to go on to new highs. (You have to click on the double right arrow at the bottom of that to see the latest one.)

It's currently no more than an (energy intensive) crap-shoot. Volatility like that, almost certainly due to a single person's willingness to accept or not accept it as currency (for a Tesla)?
It's nothing like a currency. A limited commodity for barter of real utility primarily for those who wish to keep their (illegal) transactions hidden. They'll take the risk to keep out of jail.
Ooops! Excuse me. It's just dropped another 9.3 % from it's already depressed value.

I don't actually know a lot about cryptocurrency...yet, but a friend who claims he does, was telling me that Bitcoin is un-sustainable, especially for the future, due to the need for mining and the energy that requires.
Other forms of crypto that don't require mining have a better future sustainability, especially if it is adopted by a larger world population.
I am not sure if this is a correct assessment or not, but that is what I was told.

There can only be 21M bitcoins, and over 18.5M have already been mined. The transaction cost (updating its blockchain) is more of an issue, but not so much if it's used as a store of value instead of for regular trade, in the same way that you could compare gold (store of value) to paper (for regular trade).

The only thing that "sustains" them is a type of group madness; the shared believe (hope) in a particular "big win (lie)". In the old days, one hung out at the track.

In the mid 1970s we were working on a message switching system for QANTAS.
Someone sat down and did the calculation. The threshold for 'put it on 1/2" mag tape and call a courier' to get data from Sydney to Melbourne (500-odd miles) was a shade over 2 megabytes.
QANTAS were paying $250k a year for a leased line Sydney to San Francisco. 9600bps.
Recalling that makes me feel really old.

In the late '70s I worked for the Rail Technical Centre in Derby. HQ (London) used to send mag.tapes up by train. All was well until they started doing some experiments with 25Kv overhead electrification (not actually powering much, just different designs of catenary wiring). Then the tapes were arriving empty, or at best unreadable. Took about two weeks for them to suss out the problem. That was one test of the overhead wires they'd not planned!

That strikes me as an unrealistic goal.
A better goal would be to learn the basics first.
The difficult we do right away...
...the impossible takes slightly longer.
