"Blockchain technology is energy-intensive..." => No, it doesn't have to be.
Let's look at Proof-Of-Stake, an alternative to the energy-intensive Proof-Of-Work algorithm.

Proof-Of-Work is the name of a cryptographic algorithm that is used for some blockchains when new blocks are to be appended to the chain.

Let's take a higher-level look at how this one works, shall we?
\U0001f9f5\U0001f53d
Proof-Of-Stake is another algorithm, designed to create distributed consensus on a blockchain while being less energy-intensive and more scalable than Proof-Of-Work.
While having the same goal as Proof-Of-Work, distributed consensus, the process is completely different.
A Blockchain that uses Proof-Of-Stake chooses a node to create and append the next block randomly. This process of appending a new block to the chain is usually called "forging" and not "mining".
Whenever a node is chosen to forge a new block, the stake's age is reset to zero to distribute forging among all nodes ...
There are many other factors that can be taken into account and they are usually as individual as the blockchain using Proof-Of-Stake. Taking a look at the specific blockchain's whitepaper usually helps you to decide whether the chain is legit ...
When chosen, a forging node checks whether all transactions for the next block are valid. It then signs the block and appends it to the chain.
Well, we are at the end of this thread, and I hope you now understand Proof-Of-Stake, the alternative to the energy-intensive Proof-Of-Work a little better.

World economies currently suffer four major redistribution challenges:
The most important is increasing government stealth use of the monetary system to confiscate assets from productive actors.

That process is exacerbated by "Cantillon Effect" transfers to interest groups close to government ("the entitled class," public sector workers, the medical industrial complex, academia, etc....), which is destroying much of that wealth /3
The shadow nature (see Keynes) of government inflation makes the process unidentifiable, un-addressable and undemocratic.

Where should I start?
1) Is Blockfi profitable?
2) How much money does BlockFi have on its balance sheet?
3) Is the yield that BlockFi pays to its depositors earned or subsidized by billionaire investors?
4) Has BlockFi ever been profitable?
5) Are you planning to go public?

I'm going to do two history threads on Ethiopia, one on its ancient history, one on its modern story (1800 to today). 🇪🇹
I'll begin with the ancient history ... and it goes way back. Because modern humans - and before that, the ancestors of humans - almost certainly originated in Ethiopia. 🇪🇹 (sub-thread):
The first likely historical reference to Ethiopia is ancient Egyptian records of trade expeditions to the "Land of Punt" in search of gold, ebony, ivory, incense, and wild animals, starting in c 2500 BC 🇪🇹
Ethiopians themselves believe that the Queen of Sheba, who visited Israel's King Solomon in the Bible (c 950 BC), came from Ethiopia (not Yemen, as others believe). Here she is meeting Solomon in a stain-glassed window in Addis Ababa's Holy Trinity Church. 🇪🇹
References to the Queen of Sheba are everywhere in Ethiopia. The national airline's frequent flier miles are even called "ShebaMiles". 🇪🇹

A THREAD ON @SarangSood
Decoded his way of analysis/logics for everyone to easily understand.
Have covered:
1. Analysis of volatility, how to foresee/signs.
2. Workbook
3. When to sell options
4. Diff category of days
5. How movement of option prices tell us what will happen
1. Keeps following volatility super closely.
Makes 7-8 different strategies to give him a sense of what's going on.
Whichever gives highest profit he trades in.
2. Theta falls when market moves.
Falls where market is headed towards not on our original position.
3. If you're an options seller then sell only when volatility is dropping, there is a high probability of you making the right trade and getting profit as a result
He believes in a market operator, if market mover sells volatility Sarang Sir joins him.
4. Theta decay vs Fall in vega
Sell when Vega is falling rather than for theta decay. You won't be trapped and higher probability of making profit.

I am quite different from your style. I follow the market's volatility very closely. I have mock positions in 7-8 different strategies which allows me to stay connected. Whichever gives best profit is usually the one i trade in.

Anilji most of the time these days Theta only falls when market moves. So the Theta actually falls where market has moved to, not where our position was in the first place. By shifting we can come close to capturing the Theta fall but not always.

This week has been great so far. The main aim is to be in the right side of the volatility, rest the market will reward.

There is a difference between theta decay & fall in vega. Decay is certain but there is no guaranteed profit as delta moves can increase cost. Fall in vega on the other hand is backed by a powerful force that sells options and gives handsome returns. Our job is to identify them.
