You buy for $50 of bitcoin and pay around $2 of fees, 1 year later your bitcoin is worth $100, you want to spend that money now but the fees are $60 to move your btc so you have $40 left now.

Depends how important it is for you personally to make the transaction right now. Its around $20 for a simple transaction and for full and final settlement of the transfer of funds, still mega cheap in my mind. You can always wait for a more favourable fee situation. Or just fire off your transaction now at your preferred fee rate and wait. Worst case is your funds go nowhere.
