I am using Binance primarily and also using Kucoin, Huobi, Gate.io and Coinbase. I would suggest you to start with Binance as it's simple and has a good UI compared to other exchanges and also it's secure. If you start using Binance, Kucoin, Huobi and Gate.io then you can find all the pair in any of these exchanges.
Learn to use Binance gives you some good edge in terms of trading. It's an all in a package that gives end users
the comfortable journey from this investment, you can trade, stake and invest using this platform, while the
good catch is P2P system in most countries, Binance can give you anything that you need.
Just take time to do your research about the platform that you will going to use to avoid being victimized
by both scammers and hackers.
