Sri Lankans have started to find about cryptocurrency related projects from a considerable time period. But because of a lack of fluency in English and other international languages, they have to face a lot of inconveniences. If there is Sinhala translations of your project related details such as white paper, ANN thread and project news, then the wealthy community who have less fluency in English in SriLanka will be able to understand the project well and to make large-scale investments in your project. I think that will be caused to build a strong and large community for your project from SriLanka too.
I have been engaged in translating cryptocurrency related materials into Sinhala. As per my experience most definitely that would be immense assistance for your project. If you are interested I can do the Sinhala translations of your project related details.
