The future of trading, is decentralized exchanges, and atomic swaps. With decentralized exchanges, you have a software, that has a wallet, that you control.

Atomic swaps, are on chain transactions, that you can exchange coins, on the two different blockchains. Eventually, this will become the norm in a couple of years.
