How do I deposit money into my crypto account?

I'm new to the world of cryptocurrencies and am wondering how I can deposit money into my crypto account. Could you please guide me through the process step-by-step? I've heard there are a few different options like bank transfers, debit/credit cards, or even using other cryptocurrencies to fund my account. But I'm not sure which one is the most suitable for me. Could you elaborate on the pros and cons of each method and how secure they are? Additionally, are there any specific fees or limits associated with these deposit methods? Your help in this matter would be greatly appreciated.
