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.
Yes your right, every coins has their own issue, so for me i will combine those coins that fits for me, like i made a trade in bitcoin, ethereum and bch, then covert in xrp and send to my wallet from exchange for more faster and cheaper, then convert it again to bch and withdraw to fiat, meaning if i do to stick to one crypto, the fees are high like in bitcoin to be send to my wallet and sometimes it takes too long, so ive learned to use those altcoins for me to make transactions more faster and cheaper.
