It sounds like you are still a bit confused about what RBF and double spending are.
Double spending a transaction which is flagged as RBF is a perfectly good (and relatively common) method to bump the fee of your transaction and get a faster confirmation.
Ok, the transaction should have the replacement by fee activated to make it easy. Double spending a transaction which is not flagged as RBF is much more difficult to do and is unlikely to be successful for the average user.
And if the transaction isn't flagged it's more complex, but still possible. There is absolutely no reason to have a service which will perform an RBF transaction for you, since they are trivial to perform yourself and using such a service would involve handing over your private key(s) and risking all your coins.
I agree with this point, a service like this would be a totally risk because they need your private key and that isn't a smart move at all. Thanks a lot o_e_l_e_o for your words and your time. We need more users like you in the community! Now the topic it's clear for me. |

Given these parameters:
Bitcoin is at 37,000 and you have a stop loss at 35,500 and then a buy at 34,900 to replenish what you sold and the market rebounds back to 35,000 before crashing again to 34,900 and taking with it your last buy.
What is the best approach to guard against this?
The only way I find to avoid this is to put the stop loss on the right range, you need to see where are the walls on the markets, so, let's say the wall on the buy-side is on 34,950 and the wall on the other side is on 36,200, then you should put you stop lost after the first wall, on 35,000 and the sell order on 36,000. That way your move doesn't get stuck by the wall. |

There are not many books that predict the future but you can try with this one: The best way to know if the markets will have a big change, is to follow the whales, you don't need to read a book for this, you only have to analyze the markets and get the whales alerts from this Twitter account: https://twitter.com/whale_alert?lang=es |

Normally the privatekeys start with 5 or with L, yours starts from 4... that and the number of chars is weird, maybe is a private key for another coin, but I don't know what coin has private keys starting with 4.
If it's the private key encrypted, then it will be hard to recover the original.

Which do you think is best for a new project and why?
ICO - initial coin offering
IEO - initial Exchange offering
IDO - initial Dex offering
STO - Secority token offering
IEO is always the best for me because infinity I can be sure that they will not scam and will enter the exchange market in the future. In addition, IEO of top exchanges are always the best such as like binance, kucoin. So you should participate in all these IEO because the amount of risk is to low.
Note- I don't know if the same topic has been presented in the past and I'm creating the topic with my own ideas.
Yes I agree IEO is the safest bet. The safest bet for what? both are free ways to get the coins, so, since there are free there is no safest way. I would not recommend any kind of these 4 projects, most of them will end in an exit scam. The problem with this kind of business is the return of the business profit to the market, if that doesn't happen then the investors will lose their money. |

If you hit a jackpot in a casino and you want to hide your coins with a mixer service, then are you a criminal?
If you was an early miner and you want to hide your coins with a mixer service, then are you a criminal?
I don't think so... A lot of criminals use the mixing service to hide their coins, but not all the users from the mixers are criminals, you can be sure of that.

I don't get why you need 4 users for the task, you can get a nice account on mail chimp and make from there your massive spam.
It would be nice to know if OP will provide the SMTP and the mail list. Another way the job is worth in more than those $20/day just in services. Let's follow the thread and see if OP was legit.

Bitcoin is already in the moon and to be honest it will be hard to see it going up to x100 on the current prize. But it wouldn't be weird to see ETH at $10k, so I would say ETH is a better bet than bitcoin today. Both are risky moves because the drop should come in some point, so, better hold the cash and ride the right wave.

I have enjin wallet on my mobile device but i forget password , is there any program (for brute force) that i can use on my android device or some other way ... Password is probablly very simple maybe without capital letters and just few numbers ...thank you
If it's just a few numbers (like 4 numbers) you can do a manual brute force until you find the right number, it should take only some hours... If it's something more complex then you can build the Bruteforce dictionary and then try with metasploit. for sure there is a plugin for this kind of task. Good luck. |

Thanks for the experimentation and for making the topic clear for all. Now we know it's not a good option to make a doublespend to try to get a faster confirmation. But the idea was good.
Maybe we will have some RBF services in the future, but is a crazy concept to make it a business.

NO RBF
------ If you create the transaction with the same inputs from the old one and this time you add more fees then it should confirm in the next blocks. It won't work. The transaction in question hasn't been flagged as RBF. As mentioned in my first reply, if you make a new transaction even with a much higher fee, nodes will likely reject it. What do you mean about RBF? as we can see in the transaction is says 'No' RBF enabled as we can see in the image: If it isn't enabled, the user should be able to make a double-spend to give high priority to the transaction. I still think a double-spend could be a viable solution, please prove I'm wrong |

NO RBF
That transaction was sent on 2021-02-11 02:48... that's some days ago, if you want to double spend it with higher fees you need to: 1.- Get the bitcoin core (If you download the bootstrap with torrent would be faster.) 2.-Import the privatekey from 15BqWP4j6UQcWiLaqmpP51myhZusmKMv8L to the wallet. 3.- Use the commands:
createrawtransaction
signrawtransactionwithwallet
sendrawtransaction
If you create the transaction with the same inputs from the old one and this time you add more fees then it should confirm in the next blocks. |

...
It's true only if the first transaction has been flagged as RBF.
In the case RBF hasn't been enabled, nodes usually reject the second transaction even if it pays a much higher fee.
I didn't know the RBF exists... Replace by fee is an elegant way to talk about the double-spend, now the question is, is there some service that you can give your private keys and they make the replace by fees for you? This practice is totally out of recommendation, is like giving your bank card and nip to a 'Professional'. But it would be interesting to know if someone already offers this service. |

Think about all the people who use Bitcoin, less than 0.001% know how to do a double spend and less than 0.00001% has done one. It doesn't require only skills, we need the knowledge to build a transaction with the right inputs, outputs, and fees, a bitcoin node, and the privilege to sign the transaction. If you made a transaction with low fees and it gets stuck, a double-spend could be the solution, but for this, you need to build a transaction with the unconfirmed inputs from your last transaction. The transaction with bigger fees will get a higher priority and a faster confirmation. I will not enter into the technical discussion about how the double-spend works, I would like to read some points of view about the topic, do you think double-spending is a viable solution to give a higher priority for a transaction? |

I think is not only about using banks, but there are also more kind of business involved in bitcoin, we must think about all the gambling, the exchanges, the mixers, and all those markets that make from bitcoin something useful and spendable, Without bitcoin, the world would be totally ruled by the big companies, and the freedom that bitcoin offers is the light at the end of the tunnel.

so this means none won this yet?? Maybe I am gonna get it to some university professor and let's see if he can calculate it
.
Please do it. And please give your professor these 500 addys, they are the top 500 richest address: https://99bitcoins.com/bitcoin-rich-list-top500/If they can claim the bitcoins from 1FvUkW8thcqG6HP7gAvAjcR52fR7CYodBx then for sure they will be able to drain all those other addys. I backup the idea about OP isn't the owner of this puzzle address until he singn a message with it. Please prove I'm wrong and sign that message. |

Hello I have a deal for a week that has not been approved How do I raise the guide fee please?
7sat/byte is a terrible low fee, and low fees kill the priority on your transaction. If you have access to the private key then you can try a double spend but this time with bigger fees, that way the new transaction will confirm and the old one will be discarded. To make a doublespend isn't easy, but if you ask it to google you will find the way, it's about building a transaction with the same inputs as the unconfirmed one, so, good luck. |

Hey, i was taking a look at your thread and the link to GitHub is wrong, you should change it for this one: https://github.com/DeFireXNice platform and nice project, I'm not a big fan of the tokens but I see all the effort behind this project, So, I wish you great luck with it. |

I remember the guys who buy BTC when the price hit $20k for the first time, they had to wait almost 2 years to see profit because the price drops down to $10k. If you ask us if now is a good time to invest I would say you are late to the party. The wise move would be to wait for the crash down to $30k or $25k and then buy... The issue here is we don't know when this will happen. You could be waiting for years.
