Yes, it's logic. That's why hardware wallets are usually used for assets and online wallets for purchases. It's just like bank account and bank card. One is for saving and keeping money, the second is for spending.

Yes. I've had a play with both. I found the Trezor more user friendly myself but it's still pretty fiddly. Hardware wallets are still pretty first generation ish. I expect in a few years they'll be as slick as anything. In the meantime I'm prepared to put up with a bit of a grind for the sake of security.

It's the computer interfacing bit that falls down for me. With Trezor I regularly get the pin entry bit going dark and freezing on me. And the chrome app never works so I have to go through a web page instead. With the Ledger the Chrome app regularly fails to load or craps out.

It's definitely not a slick experience as it stands.

a hw wallet is nothing but a usb stick. Forget it. it's really dumb to use.  All hw wallets have backup that you need to print on paper, so why not just use a paper wallet and save yourself 100 USD?

Amm not really i currently own a trezor as well as a ledger. It isn't difficult at all to use a ledger. I do hold many alts sometimes because of the low memory i need to install then delete , this part isn't difficult but get's annoying.

Speaking of trezor it is a simple interface and you need different apps for different coins. It doesn't support too many coins but it's fine for me as ledger compensates it.

If you talking about desktop wallets then yeah they consume lot of time and energy which is why i would suggest to buy either a trezor oe ledger. It's safe and way easier and cheaper to manage.

I use both Ledger and Trezor, I find them easy to use. What is the problem you encounter with? You can always find video tutorials, just be careful not to fall for scams.

Many of these hardware wallets have been going up in price and you get locked in with server-side API's
so that's not really decentralized.

I use Jaxx and i know it has a security flaw and that's why i keep on it's own MicroSD card
that I swap in my Android phone when i use it and I would change to another software wallet
but i just like how easy it is to use and it supports about 50 other alt-coins too.

Anyone with more than $20,000 in coins should be using hardware wallets and anything
is safer than trusting brokers and agents like Coinbase in my book so it's worth the effort 

are not . I find that online wallets are very easy to use for storing and billing. I am using an online wallet to store my bitcoin. I find it quite good and safe. Use it for fast payment method I do not find it difficult to use

They are not difficult to use, i dont know why you are asking this.

You only need to open them, press a button, and that is it, it doesnt have much science right?
