battery life is a consideration, and it looks as if I will only get about a third of the life that I was getting under Windows.

obviously Bitcoin is making some demands.

I have Bitcoin running from a sub-directory in the Downloads directory, and that offends my aesthetics. I really should have planned my file structure before I started to install programs. I'm of a mind to leave it alone and live with its current home.

Normally, the (optional) fragment identifier at the end of the URL (#msg60743 in the example link) suffices to position the viewport so that the linked-to post is obvious/unambiguous. But, sometimes that mechanism isn't precise enough, like when the post is the last or second-to-last one on its page

I also sometimes lose track of the linked-to post when I scroll around the page for a bit to get some context before reading the actual post (then, I find myself going to the address bar and hitting Enter so that the browser snaps to the right post again).

LoyceV and TryNinja would probably appreciate some notice before you merge it

I do like the theory but there is one major thing stopping me from believing it and that is the official statement of the Dutch Financial Intelligence and Investigation Service (FIOD), their official website is www.fiod.nl, and the article regarding seizing Sinbad is found here https://www.fiod.nl/fiod-takes-large-crypto-currency-mixer-off-the-air/ which also contains the same image that was present in Sinbad's website.
The article explicitly says

Explain the Unspendable Transaction Output (UTXO) model

I have started a learn and earn program for my facebook group members

Truth be told, it's going to be VERY DIFFICULT to create an alternative SoV/payments cryptocurrency (besides stablecoins) that could rival bitcoin, even with a project with good marketing/bizdev. Even those with good technical fundamentals like Monero/Grin will simply just slowly but surely die in terms of attention.

The problem I've got is installing it.

storing his Bitcoin on an Electrum wallet on cold storage (that never connects to the internet).

Now he keeps the original electrum seeds on a piece of paper as well as he is storing it online on his Gmail.

Since you said your friend memorized the passphrase and 'can never forget it', then i am certain it is a weak passphrase,

if someone hacks his seed phrases both physically or online, that is of no use because he has seed extensions to the seed phrases which only he knows about.

let's say the maximum number of merits that someone can receive from an individual user should be reduced from 50 to say 30 (or less) in one month. This would not solve the problem, but it would slow down the progress of those trying to outwit the system.

In a landmark ruling, the London High Court declares Craig Wright is not the creator of Bitcoin, ending a contentious legal battle with COPA.

The future of mining lies in the use of renewable energy. Since the construction of green energy on a global scale is quite expensive, it is necessary to eliminate the emergence of excessive power capacity. To do this, it is necessary to find energy consumers with oversupplies. This is where power-intensive mining comes to the rescue. Thanks to the very flexible ability to turn mining systems on and off, they can act as buyers of excess power. With mining, it will not only be possible to use electricity rationally but also to make a faster profit from renewable sources, and such examples already exist.

One of the promising areas of the mining industry will be cloud mining, which, despite its shortcomings, has good prospects for the future. The first perspective is the increasing number of users attracted to cryptocurrency mining using cloud mining. Due to the growing interest in cryptocurrencies, more and more people want to start earning from them. Cloud mining provides the opportunity to make digital money without purchasing and setting up specialized equipment. The second prospect is an improvement in mining technology. Cloud mining companies are constantly working to improve technology to increase the efficiency and profitableness of crypto mining. This can be achieved by using new mining algorithms and improving mining hardware and software.

What if it would be possible to influence a Bitcoin node into believing the current time, is a date far in the past where the difficulty was lower, and therefore it might be easier to mine a block and get newly generated Bitcoins as a reward?

Is $weetne$$ a very good poster to earn 201 merit in 60 days with 150 post?

if you post in public the transaction that you want to accelerate, you might be in trouble because if you don't accelerate it and will hope that nodes will forget your transaction soon, then there might come someone evil who will push nodes to broadcast your transaction and it will be unconfirmed till the day recommended fees match to your TX fees.

Look at Loyce...   
Exacerbating the "no link" issue.....  
and combobulating the matter with a language barrier.

lol. thousands or hundred of thousands people already
