I've never allowed a stock to bother me if its listed as OTCBB. I'm strictly a med-tech/bio-tech investor with a long term investment approach and although most of my stocks are NASDAQ lited and fall into the category of micro cap and small cap, I do like to have a couple among the group of 17 that I consider "homerun" type stocks. The other homerun stock that I currently own which is OTCBB listed is CAMH.OB. I currently have 250,000 shares. Some of my best gains over the years have come from such stocks. If you have done your due diligence and have complete conviction in a company and where its headed, that is all that matters. The rest will take care of itself. I have complete conviction that TLON.OB will do extremely well over time. When you couple excellent leadership/management skills with growth potential going forward, you have a formula that will ultimately add up to success for the investor. All the best to you my friend.
