ok thanks for explaining!
So just another couple question if ok, when you say "send your transaction with highest possible fee" what roughly is the dollar amount for a fee like this?
Fees are defined in BTC (satoshi per byte) not USD. If your wallet allows you to set fee manually, check what are the current recommended fees and set it slightly higher:

Which fee should I use?
The fastest and cheapest transaction fee is currently 510 satoshis/byte, shown in green at the top.
If your wallet only gives you options to choose i.e. "low priority", "normal", "priority" - go for the highest ("priority") and hope it's sufficient, not much more you can do.
And which of trezor or nano hardwired wallets are better?
Don't use any of them so don't know.
