Congrats on 250 subs! 
Yes, unfortunately Patreon and Ko-fi are the next best options here, don't forget to make a banner for that!
Although if you'll be able to have PayPal sometimes (like if it's ever an option, but I know the struggle, my country is not available for PayPal right now either), I would recommend having this option too, since some people will only support creators via ink donations.
