Bitcoin is the father of all coins and with lightning network implementation coming soon, your question now should be why we need so many alt coin to perform similar function (like BCH, LTC and so on)
BTW, the transaction fee now drop to around USD$1.xx, time for bitcoin usage to fly...
Good point. Looks like op underestimates the potential of the king of the crypto world. I do realize that the current transaction fees and confirmation time when it comes to bitcoin is annoying and expensive sometimes, but this is only a temporary problem. The upcoming integration of the lightning network will help solve these problems to a large extent which is something many people fail to think about.
Also, I advise people to use segwit wallets to store their bitcoins which will further help alleviate these problems to an extent. I am currently using a segwit wallet and an happy with the confirmation time and transaction fees.
