Some other secure, commonly used options include credit and debit cards, e-wallets, cryptocurrencies, and wire transfers. Which specific method you will choose depends on the criteria you set for banking options. If you prefer 100% safety and security and short processing times, choose a credit/debit card. Wire transfers are also very secure, but you will have to wait longer. E-wallets are also safe and offer short processing times. Cryptocurrencies are anonymous and, probably, the fastest.
