Though bitcoin suffers from a serious lack of capability to support widespread retail usage. Seven transactions per second with a 30 minute to 1 hour settlement time simply won't cut it. I recently learned of a crypto called EOS that apparently has solved that problem. It's capable of doing an enormous number of transactions per second, well exceeding what Visa & Mastercard routinely do, and settling them in under a second.

It's the first crypto that is actually capable of replacing national currencies in everyday use. And it doesn't require mining. Still needs to prove itself in terms of qualifying as true free-market and decentralized, but the theory is there.

It's the cyrpto that Mike Maloney did a video about, interviewing the creator. It was posted here but is on YT.

3) FED issues a digital currency. Say bad words about FED, Bill Gates or NSA and your digital cash is gone in 60 nanocesonds.

... which is the kind of thing that will make decentralized crypto more attractive and safer to hold than will digital dollars.

Land obviously cannot be currency at all. Using actual gold and silver as money has certainly been the norm in the past, but is not directly suited for the current age where electronic purchases over the net constitute a good amount of the economy. Gold/silver back currency is the next best thing, but invariably leads to banks ending up as the fiduciary of the actual metal while people trade the notes that represent it, which is what got us where we are today.

Crypto can work effectively as a currency that renders banks largely obsolete.

There are a number of criteria that determine whether something can serve as quality money. (I'm sure you've seen this):

Generally Accepted, Divisibile, Transportable, Durable, Standardized, Stability in Value, Intrinsic value.

Among these, crypto scores quite well, lacking primarily in intrinsic value, but doing well in most other areas, including being divisible and transportable where it outscores metals.

renders banks largely obsolete.

One of the banks here in town is closing. There are four of them now and that will be reduced to three. They change names like the wind too. ;)

That's obviously not because of crypto. Probably has more to do with either consolidation or the lockdown impacting even banks.

Yes there are other branches of that bank in nearby towns.

Also I am going to be forced to get a new cell phone since the one I have now will stop working in January. This has something to do with the system the provider is using since it is being upgraded. ;)

productive farm land

When we lived in Chicago we would go out to Wheeling to pick tomatoes on a small farm that was near Palwaukee Airport.

They had shacks out back that migrant workers would use during the harvest season. But those were in disuse and the farm owners relied on "pick your own" to get along.

We went out there with the old blue Biscayne. We picked three bushels of tomatoes that were in the back seat. When we finished they wanted us to open the trunk. We told them we did not have a key for trunk. And they thought we were stealing tomatoes.

The old man was such a cheapskate he would not give us a key for the trunk. He always bought retread tires since they were less expensive than new ones. What would have happened if we got a flat? We would likely have had to get a service truck out there.

He was a cheapskate right up to the end and my sister told me she had to have his body cremated because he would not listen when she begged him years ago to get himself a place to be buried. :-/

Finally, why are central banks using blockchain as the backbone for all digital currency efforts? It has nothing to do with their fascination with bitcoin, or their fear that cryptocurrencies can become dominant (although there certainly is an element of that). The real reason is that blockchain allows every single discrete currency unit, whether it is the digital dollar, digital euro, digital yen or digital yuan, to be tracked from its digital inception, through every single transaction, and to which wallet it can be found in at any given moment. In short, blockchain-based digital currencies will allow central banks to have a real-time map of absolutely every monetary unit in circulation, and every single economic transaction, something they can't do with trillions in anonymous paper money still sloshing around . . .

Me oh my. Surprise, surprise.

Some free market eggheads have given the gov't./institutional fatheads a great idea.

Goodbye (any vistigial) economic anonymity.

trillions in anonymous paper money still sloshing around

I had some chick several years back who was on a joint U.S./U.N. operation in Syria. She told me her unit had come upon a horde of cash and that her share was $2 Million and she needed help to get it out of the country.

I smelled a scam coming on so I deleted the message. :-/

The probability that BTC was designed and launched by Rothschild-Rockefeller-Soros Agents, LTD is high.

It is easy to say that, but the proof of its origin is on Wikipedia. ;)

made $2.5 million cash deposits

Those contractors are lucky the deposits were not here or the banks would report to FINCEN. ;)

Right up there with Snopes, CNN and Chris Wallace.
