Nodes not only verify blocks, they also verify/validate transactions that go into the mempool and at every block.
Transactions are validated by all nodes. The network more decentralized than it looks like at first.

All nodes include the routing function to participate in the network and might include other functionality. All nodes validate and propagate transactions and blocks, and discover and maintain connections to peers. In the full-node example in A bitcoin network node with all four functions: wallet, miner, full blockchain database, and network routing, the routing function is indicated by a circle named "Network Routing Node" or with the letter "N."

Some nodes, called full nodes, also maintain a complete and up-to-date copy of the blockchain. Full nodes can autonomously and authoritatively verify any transaction without external reference. Some nodes maintain only a subset of the blockchain and verify transactions using a method called simplified payment verification, or SPV. These nodes are known as SPV nodes or lightweight nodes. In the full-node example in the figure, the full-node blockchain database function is indicated by a circle called "Full Blockchain" or the letter "B." In The extended bitcoin network showing various node types, gateways, and protocols, SPV nodes are drawn without the "B" circle, showing that they do not have a full copy of the blockchain.

Mining nodes compete to create new blocks by running specialized hardware to solve the Proof-of-Work algorithm. Some mining nodes are also full nodes, maintaining a full copy of the blockchain, while others are lightweight nodes participating in pool mining and depending on a pool server to maintain a full node. The mining function is shown in the full node as a circle called "Miner" or the letter "M."

User wallets might be part of a full node, as is usually the case with desktop bitcoin clients. Increasingly, many user wallets, especially those running on resource-constrained devices such as smartphones, are SPV nodes. The wallet function is shown in A bitcoin network node with all four functions: wallet, miner, full blockchain database, and network routing as a circle called "Wallet" or the letter "W."

In addition to the main node types on the bitcoin P2P protocol, there are servers and nodes running other protocols, such as specialized mining pool protocols and lightweight client-access protocols.

My transaction has been unconfirmed for a long time. What can I do?

If you have made a transaction that is unconfirmed, you can:

• Wait for a long time. Eventually, your transaction will either be confirmed or cancelled. This might take several days.
• Increase the transaction fee. This is only possible for “replaceable” transactions. To create this type of transaction, you must have checked “Replaceable” on the send tab before sending the transaction. If you’re not seeing the “Replaceable” option on the send tab go to Tools menu > Preferences > Fees tab and set “Propose Replace-By-Fee” to “Always”. Transactions that are replaceable have the word “Replaceable” in the date column on the history tab. To increase the fee of a replaceable transaction right click on its entry on the history tab and choose “Increase Fee”. Set an appropriate fee and click on “OK”. A window will popup with the unsigned transaction. Click on “Sign” and then “Broadcast”.
• Create a “Child Pays for Parent” transaction. A CPFP is a new transaction that pays a high fee in order to compensate for the small fee of its parent transaction. It can be done by the recipient of the funds, or by the sender, if the transaction has a change output. To create a CPFP transaction right click on the unconfirmed transaction on the history tab and choose “Child pays for parent”. Set an appropriate fee and click on “OK”. A window will popup with the unsigned transaction. Click on “Sign” and then “Broadcast”.

Never used a VPN before as I am always afraid that I will get myself banned on some websites  . But that could indeed be a solution to overcome the restrictions.
Can you recommend a free VPN, easy in use ?

Anyway I saw Jacksclub already accepting Tron (TRX) now, if you had Tron in your pocket you can try your luck to play in here

Yes, It would be listed in the next month.

I've been looking at Rollbit since a few months ago and bitcointalk is not the first place for them promotion and sponsorship programs have been launched on Youtube and Twitch TV maybe almost a year ago so don't be surprised if they have 200-500 active users on the chat

This is difficult since it is still difficult the inflows of money to Bitcoin, like where it came from.
But I believe if you combined retail investors, they are huge.

Yes, because for sure some miners are using their profits to pay their expenses on mining, (hardware, electricity, etc expenses). But this time, there are still a lot of willing to buy Bitcoins, so for me, miners selling their coins is okay at the moment.

Italy won again, are they back? Hard to say a young team with no superstar maybe they are just overperforming.

About Ronaldo, since he left the game earlier now FIFA could ban him for some games even if referee said "I did a mistake"

I believe I've seen a similar of this post before @OP, not the same but carries similar contest to it and I'll be so glad to tell you that, it ain't going to work. Nope, it won't! Trying to make a pump and dump through twitter groups won't work so well as to influence bitcoin price.

Those top individuals you’re talking about like EM are special after all, and we little and ordinary people can’t compare to someone who has about 50 million followers and hundreds of billions of dollars. Such people are influential precisely because of these things, and have an army of blind followers who respond to their every word - and thanks to the digital age they can create a bad or good effect within minutes.

No matter what anyone thinks of such people, it's certainly better to have them on your side than against yourself - and how much it helps or doesn't help Bitcoin time will tell. If you want to help Bitcoin, use every opportunity to explain to people what it's really about - you have the opportunity to do it every day on this forum or in real life.

As far as I know, blockchain.com fixed that vulnirability and patched it. The issue is that they refused to pay the bug bounty to the person who discovered it. It was BayAreaCoins

Web wallets are the worst (be it blockchain.com or any other service) and no one should use them.

This is a nice reward system. I guess, that is one of their selling points here.
This casino is prepared to launch their platform here in the forum, as they already have their license acquired.
And looking at their site, they are already gaining players. Not many new casinos can attract about 200 players at a time.
But yes, one thing they can add are more alts with cheaper fees. Both BTC and ETH are quite expensive these days.

I don't need that estimator, when I sent my rest of the Ethereum balance from my wallet to Rollbit wallet, I don't calculate it to know how much I have to send, cause the user don't need to send a unique number either.

P2TR is known as pay to Taproot, P2TR has not yet been activated in Bitcoin Core which means other wallets has not also been supoorting it.

Even if the offline wallet private key is seen by hackers, it can be used to steal the whole wallet from someone, it can happen to all wallets, but unlike multisig wallets, unless all the certain number of private keys require for signing is known, which will be difficult if saved offline and in different locations.

What do you think? Will Taproot activation increases the number of people and organizations that will make use of multisig wallets because of the transaction fee reduction?

I have seen the price of bitcoin increasing when I thought bitcoin will not increase so much, I am thinking now it will be better to invest now before it will be too late.

A friend of my told be about this forum, that it can be a way to help in a way I can avoid online scammers. What makes me not to invest before is because I am afraid of the internet, I was thinking money that goes into internet may be trapped there forever

coinomi, the other says electrum, I do not know which one is the best, which one can store my bitcoin in a way I will not lose it.

I think that's wrong, national teams usually have a tactic, the coaches there do know which players they want to call up, at least few days prior but usually even longer, you have a whole pool of players that you could get. Which means coaches do know what they want to do.

Problem is that players do not know that, if they haven't been the same roster of course, some nations have the exact same roster for few years, maybe one or two changes but that's fine, and in that case they can play perfectly well together, but some teams have a bit more new players, in that case it is coaches' job to explain to people what's going on, and what they are planning on doing and what the tactic will be.

I still think that everything is ready when the game starts, I haven't seen any decent coach end up getting an upsetting result with great players, if you have the players, and a good coach, you win the game, doesn't matter how recently they got together.
