Bitcoin fees are higher than any other coin. This is due to a lack of scalability and thus high mining fees, which also effects transaction speeds. Ethereum and LiteCoin have much lower fees and send much faster. XRP is cheaper and faster than that. IOTA is free but their wallet is not quite up to par yet. This market is still very young and growing. Eventually these issues will be worked out. But the great thing about competition is that you can choose which method you want to use. And if youd rather stay in the fiat world youre free to do that as well.
There are many coins which have faster speed and lower fees than bitcoin indeed. But i think we need liquidity and volumes.
A new coin usually faster and cheap, but the volume still low. That's why peoples prefer to use existing coins with a big volumes like btc, eth, xrp, etc.
