You have learnt not to put a life savings into one stock, any stock would be my advice. That amount should have been diversified rather than relying on a single newly listed venture to be the Goose that lays your golden egg. What you say about Tesserent is correct in terms of opportunity, the issue maybe is that there is plenty of competition for the same market head days and completion from global and local professional businesses.
