It doesn't matter if the fee of Bitcoin goes up and down because we still have choices like Altcoins but yeah we have choices now like using segwit wallets with a minimal fee. Though we can be affected if all these alternatives doesn't exist because of the fact that fees are way too important as it will be used in every transaction we made and I am pretty impressed because there are still ways and alternatives for to continue using Bitcoin either as an investment or as payment without having issues regarding fees. Thanks to the Bitcoin developers and the strong community that still and will still support Bitcoin in the future.
