3. Use Non-Nigerian Bank Account.
If you get foreign bank account way they support crypto for example Revolut, wise etc, you fit use am set up automatic transfer from your foreign bank account to your exchange then from there buy your Bitcoin and hold.
But don't you think the fees for using a foreign account for auto saving while you receives your salary in Naira won't be quite expensive? Because I think this should be a better alternatives for people who receives salary in foreign currencies like dollar or pounds, and not for people whose salary are paid in Naira. Because judging from the fees of the popular dollar accounts I used, which is
Cardify and
Grey, it charges a fee of $1.2 to $1.5 per each deposit. Which is quite expensive if you are to used an exchange p2p. Hence, I consider setting a reminder to be a perfect and best option among the 3 listed above.
