Should I choose BYDFi as my primary exchange?

where’s the best place to buy Bitcoin?I was looking at Strike, but then I heard it and Robinhood don’t have their own order books and just make money off the spread. Thought about some P2P Bitcoin platforms, but feels risky with no backup. I'm just worried about security and fees. ChicksX and BYDFi seem alright, though? And now, I’m kinda lost, anyone got advice?
