Even for altcoins, it's not recommended to use a close-source wallet like trustwallet. Visit the article published on cointelegraph and see how a vulnerability caused some users who created wallet through their browser extension to lose their fund.
Trust Wallet to reimburse users after $170,000 security incident

We don't know how the keys are generated on trustwallet and there is no guarantee that the same thing won't happen to those who are using their application.

Take note that your password encrypts your wallet file locally, so that someone who has access to your device can't access your fund.
Someone who has access to your seed phrase can use it to generate the same wallet and spend your fund. The thief doesn't need your password at all.


Wrong.
They can spend the fund, but there is no way to change your password. As already said, your password encrypts your wallet file locally.

Electrum is surely a trustworthy wallet and if it's in the correct way, your fund would be completely secure, but exodus is a close-source wallet and it's not recommended.
When you use close-source wallet like Exodus, you don't know how the keys are generated and whether they are stored on their server or not.

A seed phrase generated by electrum isn't BIP39. Electrum uses its own algorithm for generating a seed phrase.
Of course, since electrum is open-source, there's  nothing to worry about if you have a seed phrase generated by it and you will be always able to derive your private keys from your seed phrase.

If you want your wallet to be completely secure, your private keys should be generated using a secure tool on a secure device.
One way is to use a open-source trustworthy wallet on an airgapped device and the other way is to use a good hardware wallet.

Note that's it's recommended to generate a HD wallet with a seed phrase instead of generating a single private key. Writing a seed phrase (which is series of words) is much easier than writing a private key and in this way, you can have numerous addresses all generated from a seed phrase.
Don't forget to keep multiple copies of your seed phrase (or your private key, if you want to generate a single private key for any reason) in separate safe places.

When you bump the fee, your transaction is replaced by a new one with a new ID and you should submit the new transaction. Maybe, you submitted the replaced transaction.
I have done what suggested by BlackBoss_ before and I can confirm that it works.

It's not just you. The same thing has happened to any other image uploaded to imgur. Visit the topic created by acroman08 for more information about the issue.
Imgur images suddenly became invalid?

No. You should never accept an unconfirmed transaction, unless you trust the sender (or as mentioned by DannyHamilton, you have accepted the risk.)
Even if the fee rate is high enough, there is no guarantee that an unconfirmed transaction will be finally confirmed. It's possible that the network becomes congested and the unconfirmed transaction is dropped from the mempool. It's also possible that the sender makes a double-spend and invalidate the unconfirmed transaction.

If you submit your transaction to ViaBTC accelerator, (assuming your transaction won't be confirmed normally) the confirmation time will depend on the their share from the total hash rate and your luck.

They don't rebroadcast your transaction, when you submit it to their accelerator.

You didn't have to wait for 6 confirmations. You could make your new transaction even when those transactions were still unconfirmed.

Note that with canceling a transaction and then making a new one, you have to pay fee for two transactions and you waste some money.
Instead of canceling the first transaction and then making a new one, you could bump the fee. With bumping the fee, you replace your transaction with a new one spending more fee.

OP is right.
The problem is that when you use suggested words instead of typing the words completely, it adds an space at the end of the words.
If you type the last word manually, you will be able to select "finish".
If you use the suggested word when entering the last word, you will need to tap on "back" button, so that the extra space is deleted. After that, you can select "finish".

When you select "I already have a seed" and then enter your seed phrase, it works fine even if you enter the last word using suggested words.

What wallet did you send the tokens to?
What do you mean by being inactive? Do you mean you can't spend the tokens you received?
I guess you are using a non-custodial wallet and you can't spend the tokens due to not having TRON in your wallet. If that's the case, all you need is to deposit TRON to your address.

Take note that what matters to miners is the fee rate, not the absolute fee.
The fee paid for the parent is higher than the fee paid for the child, but its fee rate is lower. The fee rate used for the parent is 20.1 sat/vbyte and the fee rate used for the child is 93.3 sat/vbyte.


The parent isn't a small transaction. It includes 20 inputs and has the virtual size of around 1400 vbyte.

The effective fee rate is equal to the total fee paid for two transactions divided by their total size and that's what matters to miners.

You paid 28040 satoshi for the first transaction and 10,290 satoshi for the second transaction. The (virtual) sizes of the transactions were 1400 vbyte and 110 vbyte, respectively.
This means that you paid 38330 satoshi for 1510 vbyte. It gives you the effective fee rate of 25.4 sat/vbyte.

Note that the transactions will be confirmed at the same time.

It may worth mentioning that, currently you may not be able to broadcast a transaction with the fee rate of 1 sat/vbyte.
The minimum fee rate that is accepted by a node would be higher than 1 sat/vbyte if the network is congested and mempool size of the node reaches its maximum.

Block explorers usually display the time the transaction was included in the blockchain, not the time the transaction was broadcasted.
Blockchain.com first saw the transaction on May 6. That's likely the date OP broadcasted the transaction.

Canceling a transaction means replacing an unconfirmed transaction with a new one paying more fee to your own address.
Note that you can replace an unconfirmed transaction with a new one paying more fee, only if it has been flagged as RBF.

It may worth mentioning that what shown on mempool.space as total fee is for a normal segwit transaction with 1 input and 2 outputs.
If you have more number of inputs or outputs or you use legacy addresses, you have to pay more transaction fee.

I also don't think that's the case. As far as I know, they don't even allow the user to login to the account if someone is caught abusing the website. The problem should be something else.

Maybe, you had more UTXOs in the wallet generated by blockchain.com.
Take note that fee you have to pay for a transactions depends on number of inputs and outputs. The more inputs or outputs you have, the more you have to pay as transaction fee.
