Generally speaking, opening a bank account is pretty easy. Most of the time, one can simply walk into a bank, provide all of the relevant documents, and have a bank account opened for them the same day. There are even multiple banks that allow one to open an account online in minutes.
That said, actually using your bank account in the manner you want isn’t always the easiest. For example, one internet user went viral after calling out banks for low balance and maintenance fees, effectively accusing the bank of charging customers for not having money. Another claimed that his bank closed his account for making too many cash deposits.
