Hey
how can i check or calculate ETH / BTC / USDT fee for transfering from trust wallet to another wallet ?
is there any specific rule how this fee calculated ?

is transferring from trustwallet to trustwallet (internal transfer) free ?
or any wallet that have internal (free) option?

is there a difference between BTC address? some one told me that new BTC address has cheaper fee when we want to transfer BTC tho them.
