Since they are useful for the newbies developers why do they have 0$ value? They are exactly like real bitcoins but they do not participate into the main network.

Let's take this one: 35hK24tcLEWcgNA4JxpvbkNkoAcDGqQPsP

It's the address with the most bitcoins (255kBTC)

Let's assume now that a billionaire like Jeff Bezos spends 1B$ for equipment. How many hashes per second could this equipment produce? Above a million trillion hashes per second? He could do this for a month.

Could he brute force it? Or still unlikely to happen?

I would like to send 1 cent to an address and pay 452 satoshi as a fee but it doesn't let me.

This is the error:



Note that I have changed servers several times but it's still the same...

If you click you'll see some cents that people sent recently 

One question, is this bugged?

In mining, miners take the prevblockhash, the merkle root, some other stuff like version and also they set an interval called nonce that is nothing but a number that they change its time, because it changes completely the final result.

Miners also make more than trillions of hashes per second on their mining farms right? Isn't the only thing that they change the nonce? If yes, why is it always within that range and not above 10^15 (for example) ?




I hope I was clear.

Year 2020. In these days there are no people who mine blocks by themselves. As I can see only mining pools generate the new bitcoins. Therefore, halving their reward might be a little damaging... Do you think that this will be a reason that bitcoin price will increase? Due to the law of demand and supply?

I believe it will surely increase but not above 15000$. If the price had to be doubled on each halving then it would be a bubble again like back in 2017.

Now, your thoughts.

Removed.

I've seen "block size limit is 1MB", other times I've seen "block size limit is 2MBs" and others "block size limit is 1.7MBs". Who determines that? The developers of bitcoin core? Why do they change it frequently? (if they change it and I'm not wrong)

Everything started when I received a message from a bot of discord:



I registered at tradefry.com and when I received the "0.69"BTC on my account I tried to withdraw:







I hope no one will deposit that 0.02BTC...

I picture him being hided like the Unabomber  

Would you sell your bitcoins? Or scared of being revealed?  

I don't know if he has 1M BTC but he surely has many from the first blocks.

Hello I have my private key. How can I prove my ownership of my address to electrum? I don't see any insert button...

So here it talks about how bitcoin solved the double-spend problem: https://learnmeabitcoin.com/guide/mining

To abstract, if you could make 1 transaction spending 5BTC and 1 other spending 3BTC while having only 6BTC would be possible if you could make both transactions at the same time. Some nodes will get the first transaction first, and some others the second. You would have accomplished the fact that every computer would only had 1 transaction from your address.

Now what I'm trying to understand here is the removal of any conflicting transactions. How exactly do computers remove the conflicting transactions? How 2 conflicting transactions look like?

Is it like summing all the bitcoins this address has received/sent and then checking if he/she is able to spend 8BTC?

1) Who determines its value? Markets? What kind of markets? Big companies like blockchain.com ?

2) How is it getting embed on websites? If you google "bitcoin" you will see its price. This number must be set by a person, right?

Shouldn't this be a little more updated with the current value? I think I can't afford the prices...  

Why? And why the "MEMBERS" button still exists... There are many PM restrictions that wouldn't let spammers do anything.

I would like to talk in this thread about the 51% attack and correct me if I'm wrong below.

So let's assume that I have the 51% control of the network. I made a transaction that has been confirmed only 1 time and the last block is 1000.
My transaction will be inside the 999th block. What exactly I have to do in order to reverse that transaction? Rebuild the blockchain? Or building again the 999th block, then again the 1000th block and then I'll have to be the first that mines the 1001st block?

But even if it's too expensive and too unprofitable it's still possible. And I know that none of us would want that, because of the loss of fortunes (bitcoin price would drop). Some goverments tho, would want to destroy the bitcoin network and of course they can easily afford it.

Thoughts? Do you believe that goverments can control it? And please correct me if I'm wrong about the 51% attack, because I haven't fully understood it.

Based on this: https://github.com/in3rsha/bitcoin-mining-distribution

Some pools have reached really closed on doing such an attack, but I have a question. Why anybody would want an attack like this? If he controls the network (that will not be forever) what can he achieve? He can't "destroy" the bitcoin, huh?

Είδα ένα siacoin που είναι πανφθηνο και με εβαλε σε απορίες. Εαν αγοράσω 50000 τέτοια π.χ και ανέβει 20 λεπτά έχω βγάλει μεγάλο κέρδος.

Αλλά που θα μου προτείνατε να επενδύσω;

I'm talking to the people who once had 1000BTC in 2010. (for example)

Did you ever think that bitcoin would reach that price?

What is the worst thing you've done, that now you wish you hadn't done it?

I've been looking to answers for this question.

Recently I send some bitcoins to a coinbase.com's address and when I pressed "Send" it instantly loaded the payment. It's like I made a database query to coinbase.com, that fast seemed for me.

And there's the question. How fast is the spread of the bitcoin's network? When I press "Send", I send some information on my saved nodes. This means that I send them this tiny information?

I just can't get how quickly this happens. I mean, how many default nodes do I have? 500?

In order to update the coinbase's front-page it means that coinbase got the information from me.

So what happened exactly? Did I send my information to these 500 and then these 500 sent them to another 500? This means that it happened like that:

500 nodes received my information ---> 500^2 nodes received my information ---> 500^4  nodes received my information and so on?
