I went to https://www.gobrrr.me/ and I've seen that I can buy the full SeedSigner kit at 69 EUR + 11 EUR shipping to Romania with Austrian Post; I'd expect the price is not much different for Greece and it seems to be in stock.
I don't know the shop though, so I cannot vouch for it (although I like that they advertise they use BTCPay server and even seem offer a discount if paid by Bitcoin). I went there from SeedSigner website.

(Of course, with this we're back to PO Box story)

Sure, you have all the right. It's a free speech forum. I've hoped to make constructive criticism.
But if you say that "these are known problems", maybe you can dive a bit deeper with the description to allow better/more "spot on" answers?

Basically it would help to understand how you plan/intend to "use blockchain tools effectively and provide decent quality and earnings for both parties".
Or maybe you consider I'm too picky and then let's see what other answers you get.

I've just noticed that while bitcoincore.org advertises version 23.0, the bitcoin.org only has the old 22.0
Is there any problem there I've been missing? I'm asking because I've been usually sending people to bitcoin.org and not bitcoincore.org

This sounds as (sort of) Martnigale to me (too). And it was proven that such a system is basically a trap: sooner rather than later it will fail you, in one of the "unlucky" days.
When I use Martingale-like systems and my head is cool enough (!) I stop after a 3-4 loses streak and I let it go. Maybe you try that too next time.

PS. Sad story, it also tells you've played more than you'd afford to lose; make sure you're careful to avoid playing more money than just for keeping it "fun", even if you're losing some.

Imho you have to properly ask yourself what you need blockchain for and how you expect this system work. Maybe express your ideas so we don't have to guess.
I'll write down some basics/ideas I think they may be helpful for you.

While it can be great for tracking the history of a task, it will be slower than a traditional DB. And editing existing entries will probably not be possible in na simple way.
Then you have to think it over who will mine that blockchain, since without a proper reward nobody moves a finger and a proper reward for miners may mean less reward for the actual freelancers, which is not good.
And if you want centralized, internal "blockchain", imho you better go for an old school DB.

Then the payments. If you want to allow payments in crypto, you don't have to make your blockchain, instead wallets of the actual most proeminent cryptocurrencies will do.
All you have to do is to setup properly the wallets in your system to allow you act as an escrow in case of problems (2-of-3 multisig wallets may do).

---
All in all, I have the feeling you want to attract some funds by calling this "blockchain project", although the key features most probably don't need blockchain. But maybe I'm wrong.

I've never used USB miner, but I've read somewhere not long ago about similar problem and iirc one possible problem could be that the USB hub doesn't provide enough power for both miners.
So this would be first thing to check. Do you use Gekkoscience hub?

Even more, I suggest you read the Gekkoscience Newpac related thread and also ask there. It should increase (greatly) your chances get answers from people actually using exactly that miners.

In theory you're right. However, if a big enough number of people would keep tagging CZ on Twitter and ask for adding LN to Binance, I expect he will eventually go for it (but I don't know what fee will they set there).

From my understanding, you want coin control feature in Electrum for Android.
I don't use the Android version, only the PC one, but:
* according to Github, there's an open feature request for this, still open since 2019. So sorry, bad luck for you.
* the PC version of Electrum does have coin control, is that not an option for you?
* from what I've read, Blue Wallet (which has also Android version) is advertising itself as a wallet offering Coin Control feature, maybe you try using that for this job.

Interesting charts, but some people will also probably point fingers to historical charts, showing that in the previous cycle it has dropped from almost 20k to some 3k.
And we're in the middle of a cycle, it still can go lower, although I hope it won't. Everything seems to look better for now than in the previous cycle, but I'd still wait until the halving to make sure we're good.
Then we'll see for sure if you've made an unfair comparison or the things finally start looking better for Bitcoin than for stocks even for short term (for 4 years they're looking great anyway).
Of course, we all know that overall volatility keeps decreasing, we all know (I hope) that we are heading towards that (smaller volatility than stocks), still, I didn't know we're so close (or even winning already).

Clearly. I just wanted to make sure both you and the potential buyer (especially if also newbie) will go into the deal also knowing the potential nasty details. I didn't say that you or the buyer will do any of that.

I may not be 100% correct, since I don't have BitPay card, but keep in mind that:

1. Somebody may indeed buy this and use it big time and you may end up with a lot of taxes to pay.
2. You may claim at a later point that you've lost account credentials (and email too), send your ID and lock (steal) all the funds the other guy has there deposited.

All in all, I see chances for problems in both directions.

In war nothing is nice, nor fair, nor "proper".
I'd guess that Binance was nicely, but also officially, asked to block this or that. It's not the first time they obey official papers and lock users' funds.
Since the moment they started working together with the authorities and regulators (and no longer run from them), this kind of actions are pretty much expected, hence I'll even call them normal, I'll even consider them somewhat late.

While a Wall Street company is registered and basically cannot easily run away with your money, an unknown user on the internet, claiming this or that can.
While a Wall Street company is known for this job and has trained personnel doing it, an unknown user on the internet, claiming this or that has to prove himself big time.
So no, it's a bit more complicated than being "same logic".

He just picked some coins, added his one to the bucket and started writing... things, that have a big potential to get people come and correct him or argue with him.
I think that his main goal is to create a bit of drama, hence making people talk about him. And.. we've just started doing that. Yet again.


And Doge price was affected only by Musk buying Twitter. Ver doesn't matter in that equation.

You don't know, hence you give bad advises. Please try to learn more first.
As long as the hacked (total) amounts are not too big the exchanges may reimburse, but it's not a rule.
The rule is to withdraw the funds from exchanges to your own wallet where you have the private key. This is what bitcoin was made for: allow you be your own bank.
If you use exchanges as wallets, sooner or later you'll get into troubles (meaning lost money). Many already did.

For now Wiki shows PAB and USD as currencies in Panama, but not Bitcoin.

I've also read today (but sorry, I cannot find it now) that the Bitcoin-as-legal-tender may have not passed yet?
Also the English text in OP tells:

I don't see it this way. I see it in the way that while other industries are allowed to use whatever energy they want as long as they pay for it, bitcoin mining cannot. And that's, by any book, discrimination.
It doesn't matter one needs it or not. It matters whether he can, or not, if they want to.

Stablecoin issuers do need proper regulation, since they're centralized and can do a big amount of harm (and distortion of the market too).
But will this affect out-of-USA entities? I kinda doubt it. And then the shady ones - no matter how big - will still continue operating. So I fear not much will change.

I have only one question: if you're so good at this, how comes you don't trade with your own money?
And please don't say that you don't have any funds, because that would mean you've never traded.

So.. sorry, but I would not trust this kind of offers...

I've read something yesterday on this topic and imho it worth getting quoted here. Basically the "no capital gains for Bitcoin" part is not something so special in Panama.
