How much entropy is lost alphabetising your mnemonics?

Yes I know this is not BIP39 compliant and a horrible idea, but please help satisfy my curiosity with this thought experiment / maths exercise.

Two questions, one for 12 words, the other for 24.

Assuming "perfectly" random entropy to start, and the final checksum word adapted to the new order, likely not itself the last alphabetically.

Just how much entropy is lost re-sorting the words compared to the original random sort?

I don't need the "show your work" maths, more like practically speaking about current brute-forcing capabilities, "you would lose 70% of your entropy, and 40% respectively"

If not too inconvenient, something ELI5 like, how many years of effort difference?

Do Kwon’s Detention Prolonged Until 2024 As Montenegro Responds To Extradition Requests

Image
According to an International Business Times report , Montenegro’s Supreme Court decided to extend the detention of TerraForm Labs founder and CEO Do Kwon until February 2024, following extradition requests from the United States and South Korea. Closed-Door Discussions Reveal Montenegro’s Plan For Do Kwon Initially set to be extradited to the US on December 15, Do Kwon’s fate turned when the Montenegrin High Court ruled to prolong his stay until February 15, 2024. The decision stems from charges related to the collapse of the TerraUSD stablecoin, which led to significant financial losses. The High Court had previously ordered Kwon’s extradition by Friday, but his defense team appealed the decision in the appellate court in Podgorica, the capital of Montenegro. The Montenegrin Court of Appeal confirmed that Kwon contested the High Court’s ruling, vehemently stating, “I do not submit to the court’s decision.” Recent reports indicate that Montenegro’s Justice Minister, Andrej Mil...

Sam Bankman-Fried Trial Begins Tomorrow: 3 Reasons Ex-SEC Official Foresees Conviction

Image
The trial of Sam Bankman-Fried, the founder of cryptocurrency exchange FTX and hedge fund Alameda Research, is set to commence in New York on Tuesday, October 3.  This comes almost a year after the collapse of both FTX and Alameda Research. The events leading up to the trial paint a picture of alleged fraudulent activities and money laundering that caused significant damage to the businesses involved. Ex-SEC Official’s Bleak Prediction As Sam Bankman-Fried Trial Commences In a nutshell, Alameda Research purportedly took customer deposits from FTX and invested them in fictitious crypto tokens, which derived their value from the confidence in FTX’s operations.  When this confidence waned, FTX and Alameda Research suffered substantial losses, which many argue contributed to a broader disillusionment in the cryptocurrency industry.  Following an investigation, federal authorities uncovered numerous alleged crimes, leading to seven federal fraud and money-laundering cha...

April’s Crypto Game-Changers: 7 Events Set To Drastically Impact The Course Of Digital Currencies

Image
As the crypto market ended March positively, the industry gears up for an eventful April, marked by crucial developments and milestones that could significantly impact the digital asset landscape.  Crypto Halvings And Regulatory Deadlines The month starts with the Bitcoin Cash (BCH) halving event scheduled for April 2nd. Similar to Bitcoin (BTC), BCH undergoes a halving approximately every four years, which reduces mining profits for BCH miners.  On April 10, the US is scheduled to announce March’s Consumer Price Index (CPI), a vital indicator that measures the average price change paid by urban consumers for a basket of goods and services.  The Federal Reserve closely monitors the CPI as it influences inflation and, consequently, the central bank’s decisions regarding interest rates. Any changes in interest rates can ripple effect on the overall crypto market performance. April 19 marks the deadline for the US Securities and Exchange Commission (SEC) and US crypto...
