No. You won't lose merits you have received for a post, even if the merited post is deleted.


Your rank is a function of your activity and merit. Therefore, with deleting your posts, you may lose your rank due to losing activity.

If you use a trustworthy open-source wallet like electrum, that's not possible. In electrum, you sign your transactions locally. You are the only one who has access to the private keys and you never send them to third parties.


Atomicwallet is close-source and we don't know how it generates the keys. Whenever you use a close-source wallet like Atomicwallet, everything is possible.

You may lose your fund if there's a vulnerability in the wallet. If you use a trustworthy open-source wallet like electrum, you can be sure there is no vulnerability. Electrum being a SPV wallet doesn't mean it's not secure. It's open-source and there is nothing hidden from users.  

You may lose your fund if your device gets compromised. If your device is compromised, it no longer matters you were using an open-source wallet or not and it no longer matters whether you were running a full node or not.

This is not accurate. Activity is updated every hour.


If your post count is smaller than 14 * number of two-week activity periods in which you have been active, you will see that your actvity will increase after every post you make.
If your actvity doesn't increase after every post you make, that's because your post count is equal or bigger than 14 * number of two-week activity periods in which you have been active and you have to wait until a new two-week actvity period starts and you make a new post in the new period. 

If that's the case, you will never be able to have multiple active sessions. It's logging out which should affect your other devices, not logging in to your account.


You are logged out in all of your devices, once you log out in one of your devices, even if you have checked "Always stay logged in" option when logging in to your account.

Right. OP can still use coinbase non-custodial wallet, but even their non-custodial wallet should be avoided. It's worth mentioning that coinbase non-custodial wallet is close-source and there is no way to know how the keys are generated and whether they have access to the keys or not.

This is wrong.
If you use a SPV wallet, you don't need to download the blockchain and get the required data a server that is running a full node. This has nothing to do with security of your keys.
As mentioned by Helena Yu, the purpose of running a full node is helping the network and having more privacy.

Take note that for generating a secure bitcoin private key and address, you don't need internet connection at all, let alone running a full node and downloading the blockchain.

Logging in to your account using another device doesn't affect your other sessions. I have done that many times and I am sure about that. That's logging out which affects your other sessions. If you log out in one device, you are automatically logged out in all other devices.

No.
Whether or not a wallet allow you to import a private key or seed phrase depends on how it has been designed by developers.

To import a private key in mycelium, tap on 3 dot button at top right corner of the screen, select "Add account" and then tap on "Advanced & More".
After that, you will see options to import a single private key through copy-pasting or scanning a QR code.


That's what expected.
The address you want to sign message from has been already used and when you tap on "Receive" on bluewallet, it gives you another address. That's for protecting your privacy.
Take note that your HD wallet includes numerous addresses.

As long as your mobile phone is online, there is no completely safe way. Any online device is always prone to hacking.


It's true that you can't export individual private keys from trustwallet, but you don't need to do so at all. The seed phrase generated by trustwallet is BIP39 and that's supported by bluewallet and many other wallets.

On a side note, I recommend you to avoid any close-source wallet like trustwallet.

There are many wallets that you can use for generating bitcoin addresses.
For example, you can use Electrum (which is one of the best SPV wallets) for generating legacy and bech32 addresses. You can also use Sparrow for generating all four types of addresses mentioned above. 

The signature is verified and the message proves that you own bc1q7vr2ge5392zp3rwn6q60skp98dlce7au8qaztv, but no transaction has been made from that address to bc1qkf6knnzvnu2h47g8wa7h4hx7k3vm8tcqyc27xy.
The bc1qkf6knnzvnu2h47g8wa7h4hx7k3vm8tcqyc27xy has received 0.007 BTC in a transaction including 7 inputs and none of those 7 addresses is the address you signed message from.

OP is talking about a private key and that's different from a seed phrase.
Th most common format of a private key is WIF and that includes 51 or 52 characters. Even if the private key OP is trying to find is a mini-private key, it would include 22 or 30 characters and as mentioned by mocacinno and LoyceV, that can't be brute-forced.


OP, anyone sending you a personal message to help you find your private key or asking you to send/him a personal message is a scammer.

Since you said your country won the 2015 FIFA U-17 World Cup, you should be from Nigeria.
Nigeria is one of the most successful teams in history of FIFA U-17 world cup with winning the title 4 times, but they haven't qualified for the 2023 tournament. As mentioned by OP, CAF qualified teams are Burkina Faso, Mali, Morocco and Senegal.

Mining without any hardware? That's not possible at all.

Take note that anyone claiming that you can mine bitcoin without any need to hardware and just with going to a website, running an application, etc. is a scammer.
There are also services called cloud mining that claim that they sell you mining power. They are scam too.

They have a software wallet too and that's probably what Agbe was talking about. Of course, he/she is wrong about safepal being a custodial wallet. Even their software wallet is non-custodial and gives users full control over they fund.


As far as I know, there is no coin control on Safepal software wallet.

Iran, South Korea, Japan and Uzbekistan advanced to semi-final of AFC U-17 asian cup and qualified for the final tournament of FIFA U-17 world cup.


There is no FIFA U-21 world cup. We have U-17 and U-20 world cups.

Both bluewallet and electrum are good. mk4 suggesting bluewallet doesn't mean you can't use electrum.
You can use electrum or bluewallet for any amount of bitcoin, but note that any online device is always prone to hacking.
If you have a significant amount of bitcoin and you want your fund to be completely secure, you should create your wallet offline on an airgapped device or go for a good hardware wallet.

OP already said that he/she is using Safepal.  


You are right that Safepal is close-source, but it's not a custodial wallet. Safepal is non-custodial and gives users access to their private keys.


OP is asking how to spend a particular UTXO and it's required to use coin control for that.

Not all non-custodial wallets support coin control.
Safepal (which is being used by OP) is a non-custodial wallet, but it doesn't allow you to choose which UTXOs you want to use for your transaction.

To OP:
I recommend you to avoid safepal. In addition to not supporting coin control, it's close source and we don't know how secure it is.

You misunderstood that post.
I said binance academy has predicted the halving to be 293 days later while they say the average block time is 9.89 minutes. I even shared the link.
In the next part of my post, I said that with considering the average block time of 9.89 minutes, the halving should be 303 days later.

293 days was what displayed on binance academy and 303 days was what calculated by me.
