Tether is an insolvent fractional reserve scam, is based on a fiat which continually loses value, and Tron and BSC are both centralized scams. The number of things which could go wrong holding this combination long term is huge, and even if everything goes right, all that will happen is you will continual lose value. I would gladly pay $22 in a withdrawal fee if it meant I could hold bitcoin instead of these trash coins. If you are talking about a total value of ~$2,000, then inflation only needs to be 1% over the next year (it will be  higher than this) for you to lose the value of Binance's ridiculous withdrawal fees if you choose to hold a stablecoin instead.

Further, given how much trouble you have had in the past doing fairly simple things involving your Ledger Nano, I would think you wouldn't want to install another altcoin app on it and manage additional accounts. Just stick to bitcoin and top up your bitcoin wallet.
