Hi all thanks in advance, very new to hard wallet,
So if I buy Bitcoin from 1 exchange and Bitcoin from another exchange and send to my trezor T wallet does it all just go to the same address on my wallet?
Which wallet your btc goes into is up to you.
When withdrawing btc from the exchange, which wallet you fill in the btc address, which wallet the btc will enter.
Hei Mick1
It all depends on how you manage your addresses.
BTC allows for the creation of a plenty different addresses.
You can choose to use one for each withdrawal or you can use the same address for both exchanges.
Usually using different addresses is advisable for more privacy.
The wallet that you choose to input/create these addresses is the wallet your btc will show up in.
Hope this helps
