No, your solution is just to resign from shopify and host store yourself, for example woocommerce.
See? With own hosting you have many, many operators, even in Bangladesh like:
https://www.portwallet.com/en_US/index.html
and you can easily take payments from whole world.
Your problem is not country but popular USA services like shopify or stripe, who are ignoring most countries. Thx, we have local operators and thx to Visa/Mastercard, can accept cards globaly. Justt look for operators in Bangladesh
Stripe map is just insult
Seems, according to Stripe, the Iron Curtain still exist, no matter that half of not included Europe is in EU and EEA.
This is illegal because if you want to operate in European Union, you have to serve your services for all union countries.
I think Stripe can have serious legal problems if someone get interested to this.
