I am using BTC for 2-3 years now not just investment but as currency , I used it regularly for receiving my freelancing bill also paying server domain other stuff online but now a days the fees is giving me heart attack , literally I cant pay 11-15$ transaction fee to buy 20-25$ domain/server. I can see many people are saying to use alt coin but not all services accept alternative coin , so only suggestions I have to use old school method like paypal or card 
Yes as far as I know if bitcoin will become more expensive or higher the transaction will be more higher too because it is based on some point that bitcoin has already do from the very start. And actually alts now is not yet exposed as Like bitcoin exposed from the people. So, it is not yet totally accepted because of it's not yet exposed. For today I advice you to transact with cards or paypal where you will spend money for transactions in a very cheap way not like bitcoin transactions.
