That's quite handy, but not necessary IMO.
I do think that it's
definitely a want, not a necessity. If you would want convenience without having to pull out a cable and put into your phone or PC, it's going to save you some time, but if you don't need it, better invest it in something else.
You have to go through each word and select each letter using the 'left' and 'right' button, then choosing it by clicking with both buttons.
This can take quite some time until you have entered your 24 words.
I can imagine the hardship that you might have to go through with having that many words and manually doing it. I'm planning to do it to my Nano S and I think it would gruesome to go through.
You shouldn't be confused with my post since you post link to back pack bundle in your post :
I honestly got confused with that. Maybe I was occupied with something else in my mind back then. So that is what you are referring to and I got confused with just a few words.
Regarding some discount form Ledger, why not save some money if they offers something like this every year. But maybe we can save even some BTC if price is go up in next months, it is not same if you pay 0.015 or 0.01 for same device.
I do believe that saving that much would be helpful for the future, or not just save, invest in another thing. The best investment, in my opinion, is knowledge/education.
I wouldn't regard Monero as worthless. It is the only coin which offers a decent anonymity. It is not natively supported by ledger live.
Additionally, there are very few wallet which support Monero, because Monero is very different (on technical level) than other cryptocurrency.
I do think that Monero is a secure cryptocurrency and protecting you with its privacy, having that stealth addresses, etc. I don't think people who do not have a technical background with regards to computer terms or cryptocurrency terms, and they would have a hard time understanding Monero.
