Any other thoughts about that? I mean companies are getting hacked and the information obtained is getting spread into the darkweb.

This write-up should help you — https: Thanks for the reply. I found your recommended site and videos just confusing as it covers a different wallet, and you ignored items 2, 3 and 4.

I know there is no safe place online, but some are safer than others. Someone recommended me to use uphold. I have read good things and bad things about them, but none from impartial sources. Should I be worried? The auto-scroll list thing seems to be random…. Never check your private keys here. It is red flag.

The new wallet has new addresses. With Coinbase, you have no idea what your private keys even are. And with Trezor you essentially store your private keys in this offline storage device. I get all that. But on both Coinbase and Trezor there is some record of your private keys. Trezor has to store your private keys somewhere to enable you to restore it if lost, right? So how are they really different from a security point of view?

I am new to crypto. Currently I have all the above coins on my Ledger Nano S wallet. As you said in your comment that you have all these coins on Ledger Nano S then you must have got your 24 words long seed key while setting your Ledger for the first time.

This seed is your secret key or private key in a way. Yes, I have the 24 word long seed key. That is great news. I have the big 3 coins Btc, Eth and Ltc in the ledger but there is no app for my alt coins on the ledger so I did not try to put them in the ledger thinking I could loose them.
