Thanks for the suggestions and valuations on the ledger story

Now, i had a few accounts (wallets) with relatively minor shitcoin balances on it as well. According to the ledger docs, i will have to restore all balances on the new device using the old seed, send all tokens to intermediate exchange or local client wallets, reset the new device, set it up as new, reinstall the bitcoin app and transfer Bitcoin from sold shitcoins (exchange wallet) and recovered Bitcoin (local client) to it.
Yep, seems i got some extra things to do

Don't use the ledger generated seed, I highly doubt their random number generator is actually random, true randomness is very hard to achieve. Create your own with dice then send all you coins to the addresses from that new seed directly from you old restored seed. Then wipe the device and restore with your new seed. No intermediates required and more secure. Or maybe I'm just over the top.
