You can use Bluewallet because you can download it on an iPhone. You will need the address private key which you will import, or import the seed phrase.

Na one of the downside of lifting this crypto ban by Nigerian government.
How? So if CBN do not lift the ban and something like that happens, police will not take the victim on the exchange for questioning and if possible to collect the money from the person?

Deal with people that their accounts are old and reputed on exchanges. This will reduce the chance of scam and unwanted situations.
583  Bitcoin / Bitcoin Discussion / Re: why a large Bitcoin transaction does consume more space on the Blockchain on: February 01, 2024, 04:11:46 PM
You have said it yourself. Large bitcoin transaction. The higher the inputs and the outputs in a transaction, the higher the transaction weight or virtual size (vbyte).

The type of address used is very important. Native segwit transactions have less weight or vbyte than legacy or nested segwit transactions.

For example, if someone is going to send me funds to a previously-used address, will I still receive them? Where will they end up?

Yes you'll still receive the Bitcoin because Bitcoin address never expires, they will end up in your wallet as all the address are generated Only on non-custodial platform that you can lose your Bitcoin when it's sent to a previously changed address.
If you are referring to noncustodial wallet, you will still receive the coin if the coin is sent to one of the used change addresses. Be it change address or receiving address, you can use and reuse the address if you do not care about privacy.

Thanks for the quick reply, why was one of the two tumblers censored? Is it no longer good or a rip-off?
You can read this to know the reason from here: Mixers to be banned

Because mixers are banned to advertise on this forum, that does not mean that they are no more secure. Just use their onion link on Tor browser and mix what you want to mix. Or you can go for coinjoin which are available on wallets like Sparrow and Samourai.
586  Economy / Service Discussion / Re: I need a bitcoin tumbler on: February 01, 2024, 01:33:56 PM
Of course I did my own research and read that Unijoin and [banned mixer] are the most secure and trusted Bitcoin mixers? Supposedly [banned mixer] is even more secure?
The mixers are still good.

These are their lists: 2023 List Bitcoin Mixers Bitcoin Tumblers Websites

You can also use the Whirlpool in Sparrow noncustodial wallet.

Recently, similar thread is existing: Best Bitcoin Mixer?

Is it possible that there are no issues coming from github so they are not focusing on coin control for Bitcoin?
If we were the ones to suggest coin controls for Bitcoin, would they make that suggestion a priority and be executed?

Unstoppable wallet do not have replace-by-fee and child-pay-for-parent. No where to connect it to hardware wallet. No multisig function. I can not use it to spend coins with unconfirmed transaction. Unstoppable wallet have a long way to go if we are talking about bitcoin.

I just like how it is. Things are in a way I have my bitcoin separate from altcoins.

You can not use Unstoppable wallet offline as a cold wallet. Although, you can use it as a watch-only wallet.

There are still some syncing problem.

What I think should be fixed now is the litecoin, dash, zcash and other coins synching problem. Also to support other coins. I recommend a friend of mine the wallet. He complained to me that the wallet is not supporting doge and algo and some coins that he wants to gamble with. I think a wallet should support a coin that has a marketcap of over $1 billion.

There are many bitcoin open source wallets like Electrum and Sparrow, or Bluewallet and Samourai for mobile that Unstoppable wallet can not be compared with. Bitcoin users will prefer to use those bitcoin-only wallet that has more functionality. No milticoin wallet that has more functionality that those bitcoin-only wallet if it about bitcoin.
588  Bitcoin / Electrum / Re: Remove 2FA in Electrum and use Standard Wallet instead. on: January 31, 2024, 02:50:31 PM
Assuming you have 1 BTC sent to one address on your wallet. If you want to spend 0.2 BTC, the remaining 0.8 BTC would be sent to your change address (an address on your wallet). If you send the coin and track it on an explorer, you will noticed that you sent the coin to two addresses. 0.2 BTC that you sent, and 0.8 BTC sent to an address on your wallet. So if you send all the coins on your wallet at ones, you will have no change, which means no coin sent to change address and that makes the transaction to have 1 output.

If you are sending to 1 address and the transaction has change, that is 2 outputs
If you are sending to 1 address and the transaction has no change, that is 1 outputs

If you are sending to 2 addresses and the transaction has change, that is 3 outputs
If you are sending to 2 addresses and the transaction has no change, that is 2 outputs

If you are sending to 3 addresses and the transaction has change, that is 4 outputs
If you are sending to 3 addresses and the transaction has no change, that is 3 outputs and so on.

For KYC exchanges, no need of differentiating the coins unless you have a purpose for doing so. You may separate it from coins you received from centralized no KYC exchanges but be expecting KYC at anytime.

Also have a separate wallet for coins you received from people that send you coins through decentralized exchanges. But making sure you enable Tor or using the one with in-built Tor.

There are lists of bitcoin mixers that are reputed. You can use anyone of them:

In addition to coinjoin, know that Sparrow wallet also has a Whirlpool like Samourai wallet.
591  Local / Nigeria (Naija) / Re: Crypto exchanges license difficulty in Nigeria on: January 31, 2024, 10:35:05 AM
Honestly Charles, 500 million naira capital is not enough in my estimation to establish an exchange in Nigeria. They need more funds run the company and double of it in their reserve incase there is a hack or something so that they will have enough to pay back their customers. I remember Patricia's issue and how up till this moment a good number of their clients are yet to get their funds.
When SEC brought out the guidelines, the naira at CBN rate at the time was not more than ₦450 or lower to a dollar. Dollar on I&E rate now is almost or more than ₦1000. Persistent rise in goods and services have increased and continue to increase and naira declination continues. ₦500 million of that time when SEC brought out the guidelines would be worth over ₦1 million naira of this time if not more. I am not an expert to make such analyses, but I saw the money no high, but Nigerians are complaining while not thinking about the security and safety of people's money.
592  Bitcoin / Electrum / Re: Remove 2FA in Electrum and use Standard Wallet instead. on: January 31, 2024, 09:01:06 AM
Is there a way to make this disabled 2FA wallet to a standard wallet besides sending bitcoins to a standard wallet?
You have to create a new wallet which would be a standard (single signature) wallet and send your coins to the one or more of the addresses generated there. You should know that the more addresses you send to, the more the fee required.

And also coming back to the comment of Sunderland on my first post, he mentioned that "The fees are not affected by the amount of BTC you send, but it depends on the outputs of that transaction.
e.g: Sending 3 outputs of $20 will be more expensive in fees than sending 1 output of $20."

So since there is no extra fee covering that 1 output, there are now only 2 outputs. What is the basis of the outputs? How can it be to be 1 output only?
The more the inputs and outputs, the more the fee. The second output will likely be the change address (the address you will receive your change). The difference in the fee will be minimal.

The output is the number of addresses that you are sending to. If your coin has change, it would be sent to the change address.

About the arrow, if you back it once, you will see your wallet details.

I confirm that there's no longer any extra fee when I send.
Also that the wallet synchronized with the blockchain, so you are able to spend your coins.

@Text

I tried what hosseinimr93 posted and it worked. If you do not have any other wallet on the wallet app, you can just reinstall the wallet or delete the wallet storage data, that will make your wallet new as if you have just downloaded it. To do that, long press on the wallet app and select app info which is represented with i within a circle on Android 14. Or just go to phone settings, select and click on app management to look for Electrum app and go to its wallet information. I tried it and it worked.
595  Bitcoin / Electrum / Re: Remove 2FA in Electrum and use Standard Wallet instead. on: January 30, 2024, 03:30:34 PM
@Husna QA

I was unable to recover the 2FA on Android just as Text posted. The error I got was different but it was an error. I tried it the first and second time with the same error. Test is using a mobile phone for it.

It works perfectly on desktop as it should be, but there was an error on Android Electrum.
596  Bitcoin / Electrum / Re: Remove 2FA in Electrum and use Standard Wallet instead. on: January 30, 2024, 02:55:44 PM
I followed this step but after clicking the next button, I got this error
I was unable to proceed as well, you are not wrong. Report this on  https://github.com/spesmilo/electrum

It is a bug.

I tried it on Desktop Electum and it worked. But not working on Android. Maybe a lower version may work on Android. But best is to report it so that it can be solved in the next update, or use desktop version of Electrum.
597  Bitcoin / Electrum / Re: Remove 2FA in Electrum and use Standard Wallet instead. on: January 30, 2024, 01:43:54 PM
This is what to do:

Can I do that using the existing Electrum Android wallet app?
I tried earlier, but after entering the 12-seed phrase, the finish button is not clickable.
Is there a step-by-step guide to follow?
Yes. You can use the existing wallet app. Click on your wallet name at the upper right corner -> other wallets -> create wallet-> name your wallet or go by the default name -> wallet with two-factor authentication -> I already have a seed -> input the seed phrase -> disable 2FA and proceed.
598  Bitcoin / Electrum / Re: Remove 2FA in Electrum and use Standard Wallet instead. on: January 30, 2024, 01:33:35 PM
Yes, you can disable the 2FA. While importing the seed phrase on Electrum, you will see where you will disable the 2FA.

Electrum 2FA wallet is a 2-of-3 multisig wallet. You will not pay the Trustedcoin fee which you are talking about, but the fee will still be a bit higher if compared with a single signature wallet.
599  Economy / Economics / Re: Coping with Risk. on: January 30, 2024, 11:29:05 AM
Diversify. If you like offline business, go for it. That does not mean you can not invest online. Both are good, it depends on the nature of the work. But learn about what you want to do very well before you start.

running an online investment with high risk of hack that could result in you loosing all your asset.
Do not go for the ones that are risky like putting your coins on centralized exchanges, you can hold the coins on a cold wallet instead and have full control. Also go for a better coin like bitcoin and not shitcoins.
600  Other / Beginners & Help / Re: Rate at which p2p merchant are frauding people are high - always be vigillant on: January 30, 2024, 10:56:40 AM
Yes, yesterday I almost fell for a P2P scam. Mine was the regular way these merchants always try to set people up. I had placed an order, and he approved that he had sent the amount to my account, but he did not. I told him he insisted I release it because he had sent it and I would see it in less than 5 minutes. I knew he wanted to scam me, so I left him and slept off. He then knew I wasn't going to fall for his trap and sent the money after so many hours.
If you have not received the money or the seller has not sent the complete money, do not release the coin next time. This is how some of you people will be scammed and later realized that you have done something stupid.

But waking up this morning, a friend of mine had similar issues, but this time the scammer came with a little twist. My friend told me he had placed an order for $70 since he needed some funds. As he wanted to click the sell button, the price changed, and he refreshed it again. So he bothered not to check again and procedd with the order as he got the alert in his phone he saw that the merchacnt changed the order from  $1 = 1,460 Naira to $1 = 1,270 Naira.
If the buyer has already changed the price, the exchange will notify the seller in a way it would be very obvious. Anyone that wants to sell coins should check the price of the buyer before selling the coin.
