Hello!

Sorry if these are dumb questions, but I'm trying to get a better understanding of bitcoin address management and would appreciate any good resource (I've been through the Bitcoin wiki etc, but still can't answer my questions).

The main point I'd like to understand is the linkage between addresses from a single seed/within a single wallet.

Question 1:
Let's say I have been using a seed/wallet ("A") for a bit of time and received/spent BTC from it.
If I transfer the whole balance of this wallet ("A") to another seed ("B") and then generate a new address on that first wallet ("A") to receive BTC from a new source, will it be possible to link the balance on my initial ("A") addresses to the newly created ("A") address?

Question 2:
If I use a single seed to generate a legacy BTC address and a Bech32 address, is it possible for someone analyzing the blockchain to determine that these two addresses come from the same seed / are linked?

Thanks!
