Could you please elaborate on the steps involved in purchasing
Bitcoin from the PARIBU market? I'm particularly interested in understanding the registration process, verification requirements, funding methods, and the actual process of placing a buy order. Additionally, I'd like to know if there are any fees associated with buying Bitcoin on PARIBU and what are the recommended security measures to ensure a safe and secure transaction. Additionally, are there any limits on the amount of Bitcoin one can purchase, and how long does it typically take for the transaction to be completed?
