Thats right and probably one of the reason why newbies are more interested to invest in LiteCoin and Bitcoin Cash and that probably why it is going to the mooning to terms of price but they do not know the technology behind and bitcoin = bitcoin and no one can replace that. Others will remain as alt coins [period].
Yes, Bitcoin was designed with relatively high transaction fees in mind. It is the justification for the maintenance of the blockchain once mining had reached peak production. Though no one imagined what those transactions fees would amount to in fiat terms. No one imagined Bitcoin at US$20 back in 2009, let alone US$20,000.
