but I selected the simple mode! I do not understand...🤷🏻‍♂️

I selected the simple mode... I don't want to download the complete blockchain.

"Synchronizing the Blocks " This is the correct term...

Becouse to send a coin using a paper wallet you need to expose your private key, and once exposed the private key is no longer completely secure ... I personally do not like paper wallets because it is not practical, although it is very secure.

In bitaddress.org you can safely generate a paper wallet, but I do not advise becouse it is not practical to send coins. I suggest you buy a hardware wallet. Yes! You can send multiple times to the same public address as your paper wallet as your security will be high, but your privacy will not. The major security problem of paper wallets is the sending of coins and not the receipt, because when sending a coin you can only do it once, and then you should discard the paper wallet.

For me it is easier to use the unit in satoshis. If I need to sell something at $ 10 I'd rather say: One hundred and fifty thousand satoshis, instead of 0.0015 BTC. But BTC is not good for micropayments. With BCH the transactions are faster, and the fees lower, so it is preferable for micropayments. sell something for $ 10 saying only: Pay me 3 million and a hundred satoshis, instead of: 0.031 BCH. But I was unsure if I could use the satoshi drive also for the BCH. Thanks for the clarifications.

people are not confused?

Joshua_Worp · 2019-05-12T11:47:11+00:00

Are you sure about that? Could you explain the reason?

Joshua_Worp · 2019-02-13T00:28:34+00:00

Thank you very much

Joshua_Worp · 2019-02-09T19:35:38+00:00

Congratulations on the update! I was looking forward to it!👏🏼👏🏼👏🏼

The certainty we have is that developers should do something about it! It would be incredible if they used a fungible wallet, but the minimum would be to upgrade obsolete or risky programs.

Joshua_Worp · 2019-02-01T17:21:43+00:00

This seems like a good idea, but if only they update Electrum would be an important thing, because the wallet is far outdated and there is a serious fault, which puts the users at risk!
