You are absolutely right. For any tehnokogy to serve and survive the test of time, it's a must for constant development and improvement from it's creation to what it should be able to handle currently. I see Bitcoin in such way and I believe improvement in the lapses will be done soon.
Now Bitcoin is just a digital asset since it has failed as a digital currency.
expedia.com removed bitcoin as payment option.
Not because bitcoin couldn't handle a high amount of transactions without paying a significant amount of transaction fees at the moment, it doesn't automatically mean it has completely failed already. Bitcoin will continue to be developed and will evolve positively as time goes by. Technology will move forward whether you like it or not.
