How do I transfer money from my bank account to Blockchain?

I'm curious to know, could you walk me through the process of transferring funds from my traditional bank account to a Blockchain platform? Are there any specific steps I should follow? What kind of fees or limitations should I be aware of? Additionally, how long does the transfer typically take to complete, and is there a need for any additional verification or security measures? I'd appreciate a clear and concise explanation to help me navigate this process smoothly.
