Maybe not. Shopee is known for very cheap items and I doubt there will be people wanting to pay in bitcoin. And is bitcoin that big in south east asia? But I thought that if bitcoin gets accepted in shopee, it will be a huge sign of adoption.
In the near future I think it is quite impossible because there are several reasons, I give reasons specifically for Indonesia (where I live) Shoppe users in this region are mostly middle to lower economic classes, they are more accustomed to using simple payment methods and also they do not have much basic knowledge about crypto but maybe in the future this step can be implemented because remembering that bitcoin adoption in my country continues to increase every year.
