I have a question that , If i send BTC to someone on the network. First, encrypt a message with the public key of the recipient
To add to mocacinno's reply: Take note that when you want to make a transaction, usually you don't have the public key of the recipient at all. For example, in a P2PKH (Pay To Public Key Hash) transaction, you make a transaction to a public key hash (which is known as address) and require the receiver to provide a valid signature to unlock the output. |

I am not sure I have understood you correctly. Are you looking for previous versions of bitcoin?
If so, take note that bitcoin isn't like an application which new updates are released regularly by a company.
Or you may be looking for list of bitcoin soft forks? Or maybe previous versions of bitcoin core?

In all casinos, there's a house edge which guarantee that the casino always win in the long run. This doesn't mean that the casino is a scam. It's normal that the casino should be profitable for the owners. In 2017 I was introduced by Bitsler.com
This website took me at least 2000 dollars a that time. They didn't scam you. You played at the casino and lost 2000 dollars. There is no one to blame. As far as I know, the betting is provably fair on bitsler and there is no way to scam you with unfair bets. Someone correct me if I am wrong please. |

You can see the funds by searching the public key in any blockhain explorer
I don't think there's any blockchain explorer working with public key. To see your balance and your transactions, you need to enter your address. Take note that address is different from public key. and you can access it by logging in with your public and private key together in any bitcoin thin client.
Again wrong. For accessing your wallet, your private key is enough. Your public key is derived from the private key. |

How can I see the funds I have in a paper wallet created in bitaddress ? I have my public and private code, how can I see the funds or how does it work ?
You can enter your bitcoin address in a blockexplorer like blockchair.com and see your balance and your transactions. Take note that you should keep your private key privately and should never share it with anyone. |

That might be the problem, but it should show that amount from the beginning when you input the numbers. The way it works seems like a bait and switch, but I wasn't sure.
Yes, that's the problem. I just tried it to see how it works. As you said, the exchange rate may change once you enter your receiving address. I tested it with exchanging 0.2 BTC and 0.002 BTC to USDT. Currently, they give 3929 dollars for 0.2 BTC and 34.34 dollars for 0.002 BTC. Given that the current price of bitcoin which is around 20,040 dollars, the fee for trading 0.2 BTC is around 2% while it's around 14% for exchanging 0.002 BTC. |

Aren't you trying to exchange a very low amount?
I think there's a limit that the fee cannot be less than. That makes the fee higher in percentage when dealing with low amounts.

To add to what mentioned above by other users:
If you click on "+Merit" button on any post, you will see a message showing number of your sendable merit.
Here is the message.
You have received a total of X merit. This is what determines your forum rank. You typically cannot lose this merit. You have X sendable merit (sMerit) which you can send to other people.

Yes but isn't the number of blocks consecutive meaning that the same people can be more favored than others
No. for example I don't understand it but I am assuming the last round to had block 709500 as a number while a week later to have the block number of 750.000,aren't the persons with ID near these numbers and a huge number of tickets in this range more favored than the others? No. Your ID number has nothing to do with your chance of winning. I am having difficulties at understanding this of course unless the block numbers between two weeks can be numbers much apart than the ones I described here.
The block number isn't used in the calculations at all. That's the block hash which is used. As mentioned in my previous post, the block hash is a 256 bit hexadecimal number and no one knows that until the block is mined. When the list of user IDs and their tickets numbers is published, the block hash is still unknown and it can't be in favor or against any user. |

While I believe it to be independent the fact that they do a certain Bitcoin block number and add 12 or don't know how many blocks to that number shows that they cannot be independent because they depend on this number and the people who have an ID near such number together with a big number of tickets tend to be winners more than others,therefore variance plays not that of an important role.
Different rounds are completely independent from each other and the result of a lottery round has nothing to do with what happened in the previous rounds. Take note that the block hash which is used for determining the winner is a 256 bit hexadecimal number and there is no way to know that until the block is mined. |

The image you shared is irrelevant to your post.
Your post is about dust attack in bitcoin while you have shared an image from your TRON transactions.
As mentioned by Charles-Tim in the first reply, the dust limit for legacy addresses is 546 satoshi. That's 294 satoshi for segwit addresses and your transaction will be rejected, if you send lower than the limit.
In the image you shared, we see a TRON transaction sending 0.000012 TRX and I don't know whether there's any dust limit for TRON transaction or not.

Mycelium is very safe to use to store Bitcoin, in addition to private keys under our control, Mycelium is also safe from online theft.
There is no online wallet with the feature of "being safe from online theft". If you want to be 100 secure and protect yourself from getting hacked completely, you should generate your wallet on an airgapped device and your keys never connect to the internet. Otherwise, there's always the possibility of getting hacked. A good wallet allowing you to generate the wallet and spending the fund offline is Electrum. I doubt that's possible in Mycelium. Someone correct me if I am wrong, please. |

Then I was reading up and read that I shouldn't store my coins on exchanges because if they're hacked you could lose everything.
Right. You shouldn't keep your bitcoin on an exchange and that's not only due to possibility of getting hacked. You shouldn't keep your bitcoin on an exchange, because in this way, you give them full control over your bitcoin and they can freeze your fund at any time for any reason. It's always recommended to use a non-custodial wallet or a hardware wallet. Take note that you don't have to use a hardware wallet. You can use electrum and if you want to be 100% secure, you should install it on an airgapped device. If you want complete security and you can't use an airgapped device for any reason, you should use a hardware wallet. |

What do yall think about Bitaddress.org ?
If you use bitaddress offline on an airgapped device and not the online page, it's secure. (The source code can be accessed through github). But I still recommend you to use electrum. If you use bitaddress, you have to backup a private key for each address. With electrum, you can backup numerous addresses with a seed phrase. Backing up a seed phrase is surely easier than backing up a private key. I haven't heard much about it, but I wouldn't trust it too much (if at all) because it's online.
You can download the source code from github and use bitaddress offline. |

Or there is someone else that has access to the wallet.
I doubt this is the case. bc1q.....nsa which received 0.004 BTC is owned by OP's friend. OP said that it's shown in the wallet. If someone else had access to the wallet, he wouldn't send 0.004 BTC to OP's friend. He would steal all the fund. |
|
|
|
But this would also mean that he would have consciously sent the 0.004BTC to his other address (bc1q…nsa) right ?
It's impossible that you make a transaction to an address and then a partial amount of the fund is sent to another address automatically. The only person who can make a transaction from an address in the one who owns the private key of the address. No one else could make that transaction. Another thing I’m thinking is that let’s assume it was clipboard malware, and the hacker DID have the initial address it was supposed to be sent to (bc1q…nsa), how likely do you think that the hacker would only send a small part of the funds back ? I know it wouldn’t make any sense but do you think it’s technically possible ?
That's technically possible. But It's very unlikely that a hacker would do this. Honestly the last justification I want to resort to is that my friend did something dishonest.
Unfortunately, it seems so. |

I also don’t think it could be copy paste malware because as you said why would the hacker send some funds to the correct address it doesn’t make sense.
Right. Since the 0.004 BTC transaction has been made to the correct address, it can't be a clipboard malware. Given the transactions made, I feel both addresses are owned by your friend. If you are sure that your friend is honest enough, as stated by nc50lc above, a possibility is that your friend has multiple wallets and is looking at the wrong wallet. Could there be any chance at all that this could be some sort of technical issue or glitch from either Coinbase or his Electrum Wallet ?
No. There is no problem from electrum or coinbase. If bc1.............nsa address wasn't owned by your friend, I would say your friend may be using a fake version of electrum. That doesn't seem to be the case here. |

Why is so much different from the coin market cap? what timezone do you use? 23 days is enough far. I don't know how to calculate, based on what?
Till now, 757,193 block have been mined and there are 82,807 blocks until the next halving. Assuming the average block time for these blocks will be exactly 10 minutes, the halving should be 828,070 minutes later which is 575 days, 1 hour and 10 minutes later. With this assumptions, the halving will be on May, 02, 2024. You see exactly the same date on Coingecko and bitcoinblockhalf. buybitcoinworldwide (which was used by OP) and coinmarketcap (which was mentioned by you) are using different methods for estimating the halving date. For example, you can use the average block time of previous halving periods or average block time of the previous difficultly adjustment period. No one knows the exact date of halving. |

It works if you are that rich.
What do you mean by being rich? Do mean owning 1 million dollars? No, it still won't work. It works only if you have an unlimited amount of money (which is not possible). With bigger money, you are allowed to lose more bets in a row. But take note that you have to win more times as well. |

It's better for you to read Bitcoin whitepaper first [1] after that you need to understand how exactly Bitcoin address created and how secure it is. Each Bitcoin address will have seed phrase in order to access your wallet, it can be 12 or 24 words and you can read list of the words [2]
This is wrong. It's not that all bitcoin addresses are generated from a seed phrase. Your seed phrase generates your private keys and your private keys generate your addresses. For generating a bitcoin address, you can convert a random number to a private key and then derive a bitcoin address from that private key. In this way, the address has been generated from the private key directly and you don't have any seed phrase. Take note that there is no mention of "Seed phrase" in bitcoin whitepaper and bitcoin core doesn't give you any seed phrase at all. |
