I take this opportunity to advise those who want to buy a CPU to mine XMR, to regularly look at the "engineering sample CPU" on Chinese marketplaces, there are sometimes excellent deals available!
I'm surprised that everyone is saying "no" "no" "no".
In reality it only depends on the status of your confirmation.
If the transaction is still in the mempool and hasn't received any confirmation (so it's not yet included in a block), it's possible to double-spend and get your funds back. Of course, network fees will be doubled, but at least you've got your funds back.
(I mean, for BTC and some altcoins)
There's saying "The responsibility that comes with freedom". Many cryptocurrency offer you that freedom (only you can move your coin), which means you're expect to be responsible (e.g. double check you send to correct sender with correct amount). And FYI, most coin actually can be tracked with some effort.Is it also revisable if there goes a misdirection of the transaction?
I have come across individuals done mistakes sending money to the wrong direction so the banks helps in reaching out to the receiver in request to re-send back the received fund and if by any way the receiver doesn't agree to send back the money then the bank would keep the receiver bank account on track for recovery of the fund without the account holders permits.
Although there would be a permission gadgets between the senders bank and the receivers bank before such process can be possible.
So is there a system like that?
Will Gavin Andresen, who once declared that CW is the real Satoshi, be at the trial? Who knows, maybe he changed his mind again, for the right price of course
“Wind energy, by nature, is variable and depends on wind conditions. As a result, when wind conditions are favourable, there’s an overproduction of energy, leading to instances where the price of electricity can drop below zero, reaching as low as -0.3€/kWh. Conversely, during periods of low wind, underproduction can occur, causing electricity prices to spike, at times reaching up to 2€/kWh,” said Keinänen.
But will this section be dedicated to Bitcoin wallets and blockchain only, or will all technical issues related to Altcoins be discussed as well?
By block, i think he refer to preventing certain transaction from getting confirmed or included in block. It's definitely possible with 51% attack since only the attacker can create the block with most accumulated proof of work. As for blocking node/tx created by 51% attacker, AFAIK it needs to be done manually.The story of the 51% attack was somehow always covered by the fact that it is theoretically feasible but too expensive.
I am more concerned about the attack coming from "one" holder. I think I saw somewhere that ETF holds over 110k Bitcoin, and it's just the beginning.
I'd like to hear your opinion about this event:
- Are you interested in the CMC Crypto Awards 2024? Which nomination will you vote for?
- What impact do you think this event will have on the crypto market?
- Do you consider the award nominations when making investment decisions?
but I'm more happy that even if such an attack happens one day, they won't be able to block the network forever.I am having a hard time understanding what you mean by 'block' in the sentence above, however, BTC network cannot be stopped by anyone because there is no single point of failure, and even if a 51% attack happens, which i believe it never will, it would not be long before nodes detect the malicious activity and stop validating tx's and relaying information from the malicious actor to other nodes.
All I can say is the primary reason behind new coins using PoS is related to its cost. Low cost to become a validator, this includes the energy of "mining" (staking) which connects to it's security (more validator more secured on its own way), then the possibility of having more transactions included per block, in short scalability, which Bitcoin really needs. As of now it only relies on layered solutions to scale such as lightning and liquid, segwit are not much of a help when transaction numbers rose to hundreds of thousands, you could send a transaction with low fee but it doesn't mean it won't get stuck for days which is the main problem that faced by many.
Must be the reasons why Ethereum decided to convert from PoW to PoS. Scalability is always the big question that a popular coins like Bitcoin and Ethereum have to deal with into the future. As more and more users are getting in and as the coin is getting into the mainstream, there can be a big challenge on congestion and this is especially true with Bitcoin even up to now. I recently experienced this a week ago...BTC sent to me was already confirmed by the network but it never arrived yet on my wallet so I am still waiting for it days after. Aside from scalability,

I don't think Russia government care about his tweet, especially when he already criticize Russia government few times.And that happened....when? The moment he opens he mouth he will fall from the 12 floor with 20 bullets in his back right in front of a garbage truck that will hit him so he will land in pile a toxic substances. He is a pawn and he knows that, he will open his mouth only after the he is allowed to, the fake hero of freedom who now kisses the ass of the worst dictator in the world.
I have some mining equipment, and GPUs, and I'm thinking about whether it was a good decision not to sell it earlier, I hope that maybe a similar period could come again.
It's good that Snowden is resourceful and knows how to use social networks, many of which are banned in Russia, but I wonder what his "hosts" would say to such statements? It is true that Snowden used BTC while revealing confidential information and that because of that he often mentioned BTC in a positive context, but as far as I remember there were also some criticisms on his part.
