Is it another newbie alt-account advertising these two malicious closed source wallets?
The more these two are advertised by these throw away accounts the more confident I am that they are trying to scam people. Refer to my previous reply:

Cryptography and cryptocurrency as technology will remain.
Bitcoin as the only decentralized currency will stay.
But altcoins aren't.
Almost all the altcoins we know today specially the "top" altcoins are going to die between 5 to 10 years from now.

Both statements are wrong. China has never banned bitcoin and bitcoin has never died. Millions of posts on the internet claiming otherwise doesn't make it right.

You started good but you ruined it.
ETH is just as useless as DOGE. The only difference is that DOGE is transparent about its uselessness and is known as a joke/meme coin while ETH never admitted it and in fact it fooled people into thinking otherwise. In reality ETH depends only on pump and dumps that partly happen by the ethereum foundation and partly by the scam trends through smart contracts on ethereum platform called ICO, IEO, STO, DEFI,... If the scams stopped today, ETH price drops down to less than a dollar.

That is wrong because it is out of context.

For example in altcoin market when there is blood on the streets you should run away and don't look back because majority of those altcoins that are bleeding are never going to recover and a lot of them are going to die.
Take 2017 and 2018 for example. Every single altcoin which is almost 10k got pumped during 2017, even the so called "top" altcoins got pumped a lot. Then in 2018 again every single altcoin got dumped ridiculously hard. There are coins that have lost all their value and have gone below 1 satoshi price! Obviously buying any of them is going to be foolish.

Sometimes FUD comes back to bite you in the ass.

For the past week we have been hearing the same FUDs over and over again, two contradicting ones.
1. China controls bitcoin and has more than 51% hashrate
2. China banned bitcoin and shut down all mining operations.
Meanwhile when we look at the hashrate charts we see not signs of any hashrate being "removed". If the FUD were correct we should have seen hashrate drop to 60 EHS but it is the same as before hovering around 140 EHS ±20

I feel like we got sidetracked into discussing exchanges. Although I admit trading bitcoin and making profit has become the only thing that newcomers care about but that is not what bitcoin is made for. Bitcoin was made to be a currency not an asset that you trade on some exchange whether centralized or otherwise. If you use it as a currency none of your arguments stand anymore.

I have mixed more than 0.005 and have paid lots of merchants both online and offline (face to face), even big regulated companies located in US and to this day I have never had any problems with fungibility.
Meanwhile people who have never used any mixing services or received any mixed coins have had their exchange accounts shut down!

I repeat my first post here; I'm not against more privacy in bitcoin but the problem is not with bitcoin protocol, the real problem is with centralization. Even if bitcoin were fully anonymous or if it were like this but 99% of bitcoin users were mixing their coins the centralized exchanges (and others) would still enforce anti-privacy rules. For example the exchange could force everyone to submit how they got their coins and provide a detailed transaction history to the exchange or their account would be shut down and their coins seized.

The point is that by looking at the "public blockchain" you can not know which transaction belongs to who. And you didn't do that here either, you looked at a centralized database (ie. google spreadsheets) that HCP (and others) have willingly linked their (virtual) identity to those transactions.

It's like Déjà vu. When bitcoin dropped from $6k to $3k the same media outlets  were filled with nonsense saying how price is going to fall down to $2k, $1k, etc. And now that price has fallen from $60k to $30k the same thing is being repeated but they are just adding a zero in front of their FUD.
I suppose we are going to see the same FOMO buying like that time too in a couple of weeks when price shoots past $100k.

There is no reason for a 1:1 ratio between those who make profit and those who lose money. It all depends on how people are using their heads when it comes to trading. For example I could buy a shitcoin at 1 satoshi and sell it to you at 2 satoshi doubling my money then you dump it at 4 satoshi doubling your money. In this scenario we both made profit. Those who lose money are those who end up bag holding that shitcoin thinking it will continue going up when they should have sold.

That is recovery from a very small drop such as anything around 10%, but after such a gigantic drop of nearly 50% the recovery will take a very long time partially because the investors would be very scared to jump back in and partially because the accumulation of cheap coins takes a long time.

If you check any similar huge dumps you can see they all take time to recover.

If we enter a bear market (which I find highly unlikely) it won't be "years" it will be months. Because we never reached bubbles like 2017 and we haven't touched $500k yet to start the year long bear market.

Pre-Taproot nodes that support SegWit see the new witness version (version 1) and because by default they have a flag acalled SCRIPT_VERIFY_DISCOURAGE_UPGRADABLE_WITNESS_PROGRAM that acts as a standard rule and makes the node reject any transaction containing version 1+ that comes to their mempool. This flag doesn't exist when verifying blocks so they don't reject the transactions but they also don't verify everything about the said transaction.
After Taproot (core v0.21.1+) they will do the same with witness version 2+.

This is the only word that mattered in your post.
In other words you are making a random guess based on your gut feeling and what you hope for to be true. Otherwise you have no other logic for the number you have come up with.
Conclusion: 17 million is an arbitrary number.

Having lots of shitcoins could potentially decrease the validity of cryptocurrencies as a whole specially when we have shitcoins that succeed at reaching top ranks such as the centralized ones like ETH, XRP, BCH, USDT,... This is even worse when the shitcoins are somewhat scammy too!
But I don't think such effects are going to be long term because as bitcoin grows it increases the distance between itself and other shitcoins. For example the biggest shitcoin right now is worth 0.069BTC and that is down from nearly 0.15BTC.

Having altcoins that are real projects, are secure and decentralized is a good thing but we have not seen any yet even though the altcoin market is about 10 years old. It could improve the technology and bring new innovations to the scene.
This won't happen as long as everyone (including altcoin devs) are focused 100% on making maximum profit.

It's very simple, forget about price and profit making and start thinking of bitcoin as the only decentralized currency that exists. Now you can see that there is no difference between someone who started with bitcoin years ago and someone who would start today. In fact one might argue that bitcoin is a a lot more decentralized today than it was in early days.

I wouldn't say "manged by" specially for bitcoin but news, FUD and manipulation have always been part and parcel of the cryptocurrency market, more so for altcoins. The recent crash was due to a widespread FUD campaign about bitcoin with old topics such as "energy consumption" and "China bans bitcoin".

You are right and computing the "intrinsic value" of anything has always been very difficult. People have come up with all kinds of stuff to come up with an estimation. For bitcoin some even used the "production (ie. mining) cost" which is completely wrong if you ask me because how much it costs to mine bitcoin depends on the price not the price depending on cost.

It is very simple, all ICO tokens are completely useless. So obviously when people buy these useless things they are making a bet on whether their "ticket" would win the lottery or lose. That means they have to dump it as soon as possible to get their profit out, which is why they usually get dumped right away.
This is true about all ICO tokens, there are many that are scams and the difference in scam ones is the speed at which they get dumped and sometimes the size of the initial pump they can get but the trends are identical for all of them if you ignore the size.

The only reason why you are sometimes forced to upgrade is because of Electrum itself not the soft forks that bitcoin has such as SegWit or Taproot. For example one reason to upgrade to versions above 3.3.3 was to prevent a vulnerability in Electrum letting the node you connected to to send you any arbitrary message, HTML formatted. Or upgrading to anything above 3.3.0 because of the bug in Network class.

You can see all the changes here. As you can see apart from the additional features there has been lots of bug fixes and improvements.

That is a weird conclusion you are making here! Just because some users are not running their own full node it doesn't mean they have to use block explorers. They all have some sort of wallet which they can use to check their transactions.
By the way it is not "majority" of users, most users are one time buyers who stay away from day trading and exchanges. If it were any other way and majority were indeed keeping their bitcoins on exchanges then we would have had a much more packed order books instead this thin one!

For many years I've been always saying that rich people have been buying bitcoin and accumulating it for a very long time. That includes those that are most negative about bitcoin such as Warren Buffet. We will continue seeing most of them reveal their real position and we may even get a feel of how much of their net-worth they have "parked in" bitcoin.

I don't know what kind of "crackdown on mining" this is that hasn't shown itself at all on the hashrate charts. I mean there is normal fluctuations in hashrate as there has always been and there is a big price drop compared to last month that also normally affects the hashrate slightly but apart from that we are seeing nothing else! and yet the media is running with the FUD as much as they can.
