Does anyone know which platform offers UK citizens the option to buy shares in Hyper Solar? I have accounts with HL and II but they don't do it. I've tried signing up to others who seem to say they do but they don't either. I'm not sure why it's so difficult to buy a share like this if it's someone's personal choice to do it but if anyone knows which company if any I can sign up to for this purpose, please let me know.
