Anyone have a good and simple how to for cold wallets? I want to buy one (maybe Trezor), but i never used something like this.
Any good articles or videos?

I recommend checking out the Trezor user manual as indicated above if you haven't already.

Here is also a video showing the initial setup of the Trezor that might be helpful to show you how easy it is to use:

So really no way to use trezor.io with Firefox??

Update: there does seem to be a problem, I'm getting this js error when connecting to https://wallet.trezor.io


and doesn't progress beyond displaying (non-rotating) gears and "Loading ... TREZOR Wallet is starting" message.


https://old-wallet.trezor.io/#/ still works, so it is not the browser or trezord, etc set-up.

You will have to pay the transaction fee but of course you can do this.  Not exactly sure why you would want to do it.

Also, maybe this might help (from earlier in this thread):

As an aside:  to link to byteball it is better to use the signature option, then you do not have to move your BTC just link all the addresses that currently have BTC using the signature bot.  Also, the distribution already happened, right?  I do not know when the next byteball distribution will happen.  Do you?

I am doing it that way with signatures, it's just that i had some complications and i had t move them to be able to link them with signature on another byteball client with new address.
As 2weiX said, distribution is next full moon in june, but this time dividend is 20% on every byteball you hold plus 0.0625 GB per btc. It used to be 10%
You also get blackbytes, but i dont know what to do with them yet. Everybody is selling them cheap. Maybe it's time to accumulate.

No problem here but wallet.trezor.io seems to be having a problem with the bitcoinfees.21.co API; fees set way too high. Until Trezor fixes the issue probably a good idea to use Electrum instead.

Updating firmware is not a concern. Your 24 word seed is your bitcoin; you can step on your Trezor or Ledger and destroy it, and restore your seed to a new one in 10 minutes. Back in business. You should be eager to update; firmware needs to be updated to incorporate new coins, new features. Case had a popular hardware wallet a year ago that is worthless now because they never updated firmware to adjust fees.
