Binance market in my opinion is very good because it has the biggest users right now, and for good altcoins for investment like eth, bnb, link, dot, xlm are still very good to buy, maybe you can find out better than this.
All coins at Binance are good options and have been well researched before being listed so you might want to consider investing in the long term.
Now I love DeFi coins because they are getting a lot of attention and you can certainly make high profits if you have the right trading strategy. One more thing, Binance offers very good liquidity and you can trade without having to worry about large spreads.
