Please take a look at the post history of Lattice Labs. The user got my attention after seeing his/her replies to some old topics and it seems that he/she is using AI for making the posts.
Lattice Labs made 42 posts just in 1 hour and 20 minutes and I think he/she should be banned.

Edit:
Thanks to moderators, all those 42 posts were removed. Lattice Labs's posts can be seen on ninjastic.space.

As I said in my previous post electrum is secure enough. Just because someone got hacked doesn't mean electrum isn't secure. Electrum is open-source and there's nothing hidden from the users.
As long as your device is online, whatever wallet you use, there's the chance of getting hacked.


This doesn't mean a mobile is more secure than a PC. This only means that your PC had been infected with a malware and you have been lucky that your mobile hasn't been hacked yet.

Whatever happened, there is no problem with electrum itself. Electrum (if it's used properly) is secure enough. julerz12 used electrum on an online device and Avirunes probably did the same thing.
Any online device is always prone to hacking.

It may worth mentioning that there is no "21 millions" in bitcoin code.
The total supply of approximately 21 millions (exactly 20,999,999.9769 BTC) comes from the initial block reward of 50 BTC and halving each 210,000 block.

You didn't have to pay such a big fee. You could get fast confirmation with lower fee rate.
In the past 24 hours, any transaction paying at least 40 sat/vbyte has been confirmed in the first block after being broadcasted.

By the way, as mentioned above by DaveF, OP's transactions have been already confirmed.

You won't lose the fund. Deposits that are made to the old addresses won't be automatically credited, but you will be able to credit them manually.

The time weight multiplier starts from 100 and gradually decrease to 0.

There is no huge balance that is sufficient for being successful at martingale strategy. For being successful, you need an unlimited balance.

BTC.com estimates the hash rate of pools based on number of blocks they have mined in a certain period of time.
In the unlikely event there's a dishonest person (or dishonest group of people) who owns a very big hash rate and tries to attack the network without adding any block to the main chain, it wouldn't be listed there.

Take note that bitcoin isn't a like a centralized website or application.
For attacking a website, the attacker tries to gain access to a computer or server. That's completely different when it comes to bitcoin. Bitcoin is decentralized and the blockchain is stored by thousands of nodes all around the world and for performing an attack, the attacker needs to own a very big hashrate which is practically impossible.

A seed phrase generated by electrum isn't BIP39. Electrum uses its own algorithm. Therefore, you can't use iancoleman for deriving your private keys from your seed phrase if it has been generated by electrum.


To OP:
Electrum is open-source and you will be always able to run the previous versions even if developers no longer release new updates.
Also note that your private keys and addresses are derived from your seed phrase through a standard algorithm and it's possible to derive your private keys even without electrum, if you have some knowledge of coding.

Right.
Both nested segwit and legacy multi-signature addresses start with 3 and you can't know whether the address is segwit or not if the owner of the address has never make any transaction from that.
An address starting with bc1q is a single-signature address, if it includes 42 characters and is a multi-signature address if it includes 62 characters.

Electrum is an open-source wallet and there's nothing hidden from the users. The source code has been reviewed by many people and no vulnerability has been detected. If someone got hacked, that's not electrum's fault.
Take note that any online device is always prone to hacking. If you want to be completely secure, you must use electrum on an air-gapped device.

To create a watch-only wallet using your master public key, you should select "Standard wallet" and then "Use a master key".
There is no "Import" option at all. There's "Import bitcoin addresses or private keys" option which can't be used for importing a master key.

Wrong.
Activity equals to min(14*number of two-week actvity periods in which you have been active, your post count) and that's the same for all users.
It's not that actvity is calculated in a different way for some ranks.

If you see your activity changes every 14 days, that's because number of your posts is greater than 14*number of two-week actvity periods in which you have been active. That's not due to your rank.

Did you receive those transactions on Ethereum network?
According to the following article, trustwallet doesn't show multi-send transactions.

My Incoming Transaction Is Not Showing

Yes. All your addresses can be derived from your master public key and you can use that to create a watch-only wallet. If you are online, you can see your addresses, your balance and your transactions history. If you are offline, you can only see your addresses.
Note that your password encrypts your wallet locally and it doesn't matter whether your wallet is encrypted or not.

You should never use such tools for generating a wallet.
A paper wallet should be generated using a secure open-source tool on a secure device and you should be the only one who has access to the private key. With using a centralized service like the one you mentioned, you would defeat the purpose of a paper wallet.
Also note that it's better to generate a HD wallet with a seed phrase instead of generating a single private key and address. In this way, you can have numerous addresses all derived from a seed phrase.

Whenever you make a bitcoin transaction, you define a spending condition which is known as locking script and whoever can meet the defined condition will be owner of the coins.

Any private key provides 128 bits of security and that's why brute-forcing a private key is practically impossible. In theory, it's always possible that you can brute-force a private key.

A transaction paying 0.1 sat/vbyte as transaction fee would be rejected by nodes too. As already said, any transaction paying less than 1 sat/vbyte is considered as a non-standard transaction.

The block reward doesn't come from users pocket. Miners work for the block reward.
