What is the best place to buy Cardano?

Could you please elaborate on where exactly is the most suitable venue to purchase Cardano? I'm keen on exploring various options but am not quite sure which platform offers the best rates, security, and ease of use. Is there a specific exchange or marketplace that you would recommend for making this purchase? Additionally, are there any factors I should consider before making a decision, such as transaction fees, customer support, or liquidity? Your insights would be greatly appreciated.
