The project is very good on paper, would like to check it in practice. The question is when will this happen?
You ask about X-bank ?, They will release for right now the developer doesn't have ETA about the release of X-bank. Better to wait for their announcement, creating a quality product more important than quantity.
I have heard ETA is before March 1, 2019; so, we need not wait longer than that as release must be this month.
