Although maybe not necessarily on mobile, SPV wallets have a big "market share".
But the later news made more people realize that they can be tracked and some more may have started using Bitcoin Core again (or their own servers, which need Bitcoin Core).
Also, let's not forget that far too many users (still) keep their funds in custodian wallets, usually exchanges.


I use (rarely) Mycelium. It has (plenty of) room to improve (to be overly nice), but it's not a bad wallet and it's one of the very few that support hardware wallet, which imho it's a must, especially on mobile phones.


Mycelium can do that. But.. just read forward  


Yep. Safest would be to not import them into anything that's online. If it's big funds please stay on the safe side.
Learn the basis of cold storage and import the private keys onto a system that will never go online (it can be even a Linux on an USB stick) and keep only the addresses in a view wallet online. It's enough for spending safely. Tails OS with Electrum can be such a choice, but you'll have to read about persistent storage there (and always keep a copy of the keys or seed safely, maybe on paper).
Also consider buying a hardware wallet (and move to HD wallet, based on seed). Hardware wallets are pretty safe and pretty convenient too, especially if you're not a tech guy.


If you use SPV clients your funds can be tracked to you. No other big problems.
The coins can be stolen from you with or without Bitcoin Core if your system is not secure or you make mistakes (like keeping the keys "safely" in the e-mail)


I'd start with cold storage, hardware wallets, SegWit and Lightning, especially as you have bitcoin.
Ah, please give a minute to the reading about clipboard hijackers too.
Then you can move on to altcoins/DeFi and such, although keep in mind that many of those may be just money traps (you can read about ICO era).

At an average of 10 minutes a new block is mined. But nowadays one needs special hardware to mine a new block. Usually many such hardware devices.
The miner receives some coins for that job.

All the blocks already mined can be downloaded for free by anybody connected to the network.


If I understand your problem right, then the answer is "no, sorry".
If you indeed mined blocks, your wallet should have coins in it. That's the one to recover.


If you still have that HDD and no other things (or at least not much) was written onto it, you may have a chance to recover your keys.
There are services that can do that. But you have to know a bit more than that, at least you have to know whether you indeed had coins in a wallet on that HDD.

Actually there are a couple more, especially if testnet is also taken into account: https://en.bitcoin.it/wiki/List_of_address_prefixes
And if we take all the altcoins too... sky is the limit.

However, you should tell a little more about the background of all this. For example, afaik, a QR code is simply another representation for a text, it doesn't mean that this text has to be a Bitcoin address. Also, the fact you have hidden the text doesn't mean you've hidden the (so called) address. The QR code translates to


and any QR code reader can see that.

Great link!

I'm pleasantly surprised the those making this paper actually have quite a good knowledge on the matter (did their homework properly).


I'm not into DeFi, but I'm impressed:


And the list of recommendations - from a quick read - look pretty good.



Will Australia become the first country with proper regulation for crypto? Could be. I just hope they don't "break" this when they turn them in actual laws.

I was referring to mm2543363580 (2013), kingangel (2013), StLucifer (2012), Shagnasty (2012). All are very old and have small number of posts. Quite a.. pattern.
I didn't know about kingangel, but I'm not surprised at all.



Yeah, that was my hunch too.

While the initiative is great, I think that you're doing it wrong.

First of all, aside of the posts where these guys are exposed, their usernames have to be in a properly visible list in the start of the thread, else nobody will search.

I'd add even more: maybe put in the same topic a list of good translators and a list of bad translators. This way whoever is looking of a translator can see who should he prefer and who he should avoid.
So maybe a "supporting" topic, only with these lists, is the next step to be done.

If the HDD is working, there are various software around that can overwrite existing files with garbage before removing them (wipe) and there are programs that can do similar stuff with the current free space on your HDD.
If you're under Windows I recommend SysInternals SDelete for the job, since SysInternals were bought by Microsoft many years ago, hence it should be safe.



If you want to super-sure and super-safe, why don't you just create brand new wallets and move your coins there?

Bugs do happen, so... chill down...
Did you try to use the contact form from the faq page or try to PM the owner TheQuin?
Maybe I'm wrong, but it looks like a bug to me. It may be related to the cookie settings too, but.. you better ask the support what's the problem there.

Pretty sad. I see very old accounts too. Hacked/sold? Possibly.
Else I'd expect that an user - especially if created in 2013 - would check campaign manager's trust feedback before joining.


At least this user doesn't have the signature; I guess that he may stay "under observation" until he does.


Great job! As DT2 your tag already makes the things visible.

I don't know if it was a fake breakout or there's now a bear trap, but I agree that the growth is not over. The overall sentiment is still too good.
And news like the one about Mastercard just cannot be ignored (and yet you didn't mention it).

However, sadly, manipulation in this kind of cases for "a quick buck" by the large players is known to happen now and then. So, while it's good to have all this "put on a paper", it's not new behavior, at all.

This was asked and answered in various ways, maybe more than 100 of times, why don't you just search?

Investments are not meant to be held forever, people - sooner or later - will use them. Then some are already paid in crypto. Crypto is a form of money. People do spend crypto.

The problem is that some of the (too few) payment processors nowadays make it pretty much overpriced to spend crypto directly (service fees, bad conversion rates), but I don't see why people would not buy with crypto absolutely all that's being sold, including food. LN may need to start being used by payment processors though, to make this also work in the supermarket (to not wait for on-chain block confirmation times).

Am auzit intamplator de WEBD. L-am si minat vreo 10 minute  
Mai vedeam uneori shilling pentru WEBD pe Twitter, dar din ce in ce mai rar.

Dar multe proiecte au facut "spoof" dupa ce echipa initiala a reusit sa vanda ce a minat la inceputuri. Nimic nou sub soare. Nu e o "reteta autohtona"  


Eu sunt mai moderat la de astea. Sunt si oameni cu scoala care au o pasiune de genul asta si o urmaresc, sau sunt oameni care au avut de ales intre mafia din invatamant (si salariu de prof) si a deveni instalatori si au ales partea a doua. Deci in general nu mai dau cu parul, ca am dat o data, in trecut, iar apoi mi-a parut tare rau.

Dar ai dreptate, imaginea unui asemenea proiect ar trebui sa inspire mai multa incredere decat un "barbier ninja". Omul are tot dreptul sa "propovaduiasca", dar nu e chiar OK sa fie vioara I. Iar faptul ca el a ajuns vioara I din cauza ca nu mai era altcineva mai "prezentabil"... mda... trist.


Dar sa stii ca in ziua de azi doar alt mod (chiar daca mai accesibil) de minat nu mai e suficient pentru ca o moneda sa aiba succes. Daca nu are nimic in plus, e categorisita ca shitcoin. Asa ca nu exclud ca mutarea facuta de echipa initiala sa fi fost singura desteapta pentru ei.

Mda, din pacate, sa ma picuri cu ceara si nu inteleg o iota din "limba" aia. Am incercat si mi s-au incurcat circumvolutiunile. Mai nou o evit cat de mult pot.


Nu ma mira deloc. Multumesc pentru clarificari.
Asa se si explica de ce nu a facut stirea valuri (sau tzunami).

It looks to me like a private blockchain. And if it's private, a database may be much better suited.
If I'm wrong and it's not a private blockchain, then what would be the incentives for nodes and miners to store and protect this data?

Also if it's public blockchain, people may try to get access to protected data, from medical data to people's personal info.
And I don't really see the medical and pharmaceutic industries be just nice and share tremendous amounts of information "for the common good".


So while I'd love to be wrong and this project just go on and get to results, I see it as a money hog, using blockchain unnecessarily to just over-complicate things.

That's correct. Radio communication to Mars (5-20 min) is already slow and needs improved. 3.03-3.11 minutes for the speed of light is also not great.
Some Ansible-like device/technology has to be invented first. And for that we, humans, need to find out how to send information in a faster-than-light manner. Let's be kind and say that it's gonna take a while...  

Well, the banking system has the web or relations without which crypto businesses have difficulties getting in touch with fiat dependent businesses (i.e. most merchants for now).
So these partnerships are clearly a win-win situation (from businesses point of view, not necessarily for crypto and clearly not for users' privacy). And I agree with OP:

Bar 1, c, if possible.
Thank you.


PS. Would I be allowed to post the raffle in the local board? Maybe in 29.10?

I advise you'd send some few first items to known and reputed miners, so they can prove that the miners actually mine as expected. This should grow your reputation.
Selling in batches and handling the funds through reputed escrows may also be a good idea, since you are newbie / nobody knows you yet.

Edit: if you sell on eBay or similar established store, then you can ignore my second line.

Umm... nu sunt sigur ca e chiar asa.

A existat o tentativa de SibCoin, care desi nu era virtuala, deja a avut probleme de legalitate.

Si cred ca a mai existat o tentativa de moneda digitala locala undeva prin Romania, in scop turistic, dar nu mai gasesc nici o referinta pe net. Poate imi amintesc gresit.

---

Mie mi-a scapat ca din iulie 2021 crypto este modalitate de plata oficial recunoscuta in Romania. Am gasit acum o referinta. Nu stiu daca se incadreaza ca stire, dar in alte tari s-a facut mare tam-tam 
Oare ar trebui sa pun la Presa?

I'm glad I could help.

My advice is to:
1. save that private key safely for a while
2. create a new HD wallet (with a seed), preferably supporting SegWit (so with addresses starting with bc1 or 3) which will allow you smaller fees too
3. save the seed very safely
4. Transfer all your funds from the initial address at (point 1) to this new HD wallet.


If you don't do this, your wallet will always have only one address, which is not advised, especially because it somewhat hurts your privacy.
