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.
To really make it faster and cheaper, you need to have a lot of knowledge and experience. Without these details nothing will happen. Yes, this is a very good way to make money, but so does everyone else, it requires work and time.
