That would be a very weird implementation but it could work.

WIF is a base58 encoded string with a checksum all as one whole string not separate parts. It can't be stored separately and as I said before if one character in it is "corrupted" you won't be able to decode it since the checksum would most probably be invalid.
Same with prefix, it is not something that is attached later, it can only be decoded. Again if the string is corrupted, after decoding (even if you ignore checksum validation) it is unlikely to get the same prefix.

P.S. to be honest, this looks like yet another fake wallet that you have found and are wasting your time on it.

Technically being closed source contradicts being decent and legitimate.
This is why the only reason a super shady wallet such as Coinomi has any userbase is because they offer a service that most people are looking for and can't find elsewhere (having multiple shitcoins in one light client).

Which coins? You mean the altcoins? They are not supposed to go up. They were created to be pumped and dumped a couple of times and then die. In other words, altcoins in long term are always on a downtrend.

You should be more specific about the news you think is good.

Based on this and your other topic I think you have fallen for one of these scam pump and dump groups that are "selling signals". They aren't "traders" and what they post is not "ideas". They are scammers who are posting their hopes so that some fools can buy those shitcoins and help THEM sell their bags to you.

It is actually very possible to make money even from the pump and dump shitcoins. You just have to learn to ride the pumps instead of waiting for a scammer to tell you when to buy which is always after they started dumping.

It's not a gamble, it is just bitcoin and that makes it controversial. Otherwise anywhere you look the governments look like big gamblers and all of them have been driving their economies into the ground. In US the FED keeps manipulating the interest rates and causes recession, in EU they keep printing more money and decreasing the exchange rate while increasing the inflation, ... but when it is bitcoin then all of a sudden we see articles like this

Being safe doesn't mean your keys are safe in their servers. A lot of things could happen, a hacked could exploit something in their system and gain access to your cloud accounts and take your files out of there.
For example Yahoo mail was considered secure, they've been hacked multiple times over the past decade and users have lost a lot of personal information and money because of that, me included.

Basically El Salvador is doing what a lot of others do in silence. They are taking advantage of the discount and aim for the long term potentials after the drama ends. I'm curious as to how long they are going to continue buying 1 BTC/day or at least the dedicated budget (it would take 62 days to invest $1 million assuming fixed price).

Isn't Ukraine using S300 and other Russian made air defense systems?! In any case whatever it was the infamous Sleepy Joe already confirmed that the missiles (not rockets) that hit Poland were from Ukraine.

A corrupted storage won't have a correct key string like this. You got the first byte correctly (0x80) which means there is no corruption here. Additionally if your checksum was valid, that could be another reason why it is not corrupted.

P.S. It's odd that you have so many of these "friends" who come into possession of weird looking stuff which you then try to "crack" for them...

Unfortunately not much is going to change in the long run. You may not have been around for long but when we look back at the history we can see that such hacks/scams have happened many times in the past in different sizes and forms. People talk about it, repeat the mantra of "not your keys, not your coins" and some move their coins out of the exchanges. But it all lasts a very short time. Maybe a month or two.
Then we are back to where we began. Centralized exchanges with high volumes and large number of users who keep their coins in their custody!

What you forget is that signals are a bigger scam than the pump and dump itself. Nobody can predict the pumps beforehand to give you the signal to jump onboard and if they could they wouldn't tell others! Instead they need chumps to easily obey their orders to buy a certain shitcoin and create the pump themselves. In a way the "signals" are like the scam on top of another scam.

The reason why you saw a signal and the price didn't go up was simply because the person giving the signal has already scammed a lot of people in the past that they know he is a scammer so they don't pay attention to his future "signals". Since nobody buys that shitcoin, the price doesn't go up.

They layoffs are starting and surprisingly at such large numbers. Two of the giants are laying off thousands of workers. 10,000 employees to be fired by Amazon and 13,000 to be fired by Meta which are historically the largest lay offs in these companies history.
Apart from the tech giants such as Twitter, Microsoft, etc. an additional 20k fired across 70 companies in November alone, there are a lot of other smaller companies that are also firing their employees as the economical problems grow.

We are talking about more than 70 years of war and mayhem and over 35 million innocent people killed directly or indirectly. I already told you that you should start doing your research but you still want me to list them here even though I already listed half a dozen cases!

Why do you think I consider USSR, US, NATO and Ukraine to be different from each other?! They are all the same in my eyes and they've all done horrible crimes abroad, some more than others.

My point is that these days criminals are accusing other criminals of crimes they've all committed. That's the definition of hypocrisy.

It's been a while since I've updated this topic but yesterday the mempool grew and with it the fees went up. Which is a normal thing when price volatility increases but when looking at how it all increased, things look start looking suspicious.

[Speculation]
In a natural mempool size growth we don't have a straight line because not everyone jumps on board of sending transactions at the same time specially not for a long period of time. It happens in "bursts", in other terms there should be a lot of different rates in the chart. Like this picture of a small rise from earlier this month.


However in a spam attack the attacker injects a large volume of spam transactions into the mempool usually at a fixed rate so the chart looks like the following picture which is from Nov. 14 to 15 over ~8 hours:


(Note that the count chart also shows the same thing but not as cleanly since with each new block the count drops but the "slope" is fixed which points to the fixed rate at which transactions entered mempool).

From there, it's just a matter of keeping the mempool full and preventing it from going back down to keep the fees up while avoiding a larger cost on the spammer (due to ever rising fee if the spam rate was sustained). Usually regular users do most of the work there and the spammer doesn't have to spend much:

It is not as bad as storing your coins in an account where you have zero control over your keys or your money but it it still pretty bad because those accounts could be hacked and the attacker could gain access to your coins or there could be other kinds of problems such as your account being shut down by that company for whatever reason such as violating their ToS, etc. with the same result of you losing access to your own money.

The only good choice is cold storage https://en.bitcoin.it/wiki/Cold_storage

If you really believe that then I'm not sure if you are competent enough to develop an actually secure software wallet.
You basically want people to first trust a closed source software from an anonymous person that can be malicious, then they have to hope that when malicious people found the bugs and exploits in it they don't lost their money.

Based on SO posts it seems like you want to iterate over those numbers (key cracking?!) in which case you shouldn't create them like that, you should instead parallelize the process. It all takes one line in C# or two if you want to set the number of cores to use:

Too much regulations and transparency is not good for the regulators' bosses either. Imagine if FTX were transparent, Zelensky would have never been able to take American tax payers money and invest it in FTX in first place. Not to mention that a lot of big and powerful money launderers like this would be angry and prevent that transparency laws from going forward.

They could start with 100% transparency about all their costs and everything, then ask for donations. I am certain that the bitcoin community would be more than happy to respond. I personally would make a donation to such a cause.

Besides, don't we have lawyers amongst bitcoin hodlers already? There should be some and they should bury CSW under lawsuits and make an example of him so that in the future nobody dares to repeat such attacks against Bitcoin or open source community in general.

It is worth mentioning that from Electrum version 4.0 the commands you enter in your console is no longer stored in a separate unencrypted file (called config). Instead they are stored as part of your wallet file and if your wallet file is already encrypted the command history would also be encrypted.

You can't even tell anything about the key range by looking at the public key! Address is only telling you the hash of that public key which is not only irreversible but also doesn't tell you anything about the public key either.
