Hello to long term holders,
One of the problems with a company like this is that a naive investor has no idea of the overseas competition. I would love to invest a small amount, because the potential would be huge if there were a breakthrough overseas. However, I have other companies where , after investing, I realized that there may be any number of companies offering the same sort of product/service as the company in which I have invested (a worrying feeling). Have any long term holders looked at competition (that is, for the training side, where the big money could be)?
Anyway, I will use my rather poor research skills to investigate a little.
