I was in since 1986/1987!! Ironically, bought in $3 - 5 range even back then. Went to $7, then slipped and slipped onto the pink sheets at around 16 cents. Held it for all these years. Missed a chance to buy more last December as it started heading toward a buck. I was skeptical after having seen that trick before! The MIT phased-array technology is fairly recent deal for them, and that's what seems to be giving them hope. These bio-tech penny stocks often take 10 - 15 years to take off. Luckily those years have paased for CLN, and it looks like CLN may actually rocket in the next 1 month to 2 years.
Actually, I moved to California in 1995, and it turns out CLN could not find me and turned my shares over to NY State. Now I'm in a year-long process to claim back my 800 shares!!! So I bought another 1500 around 4 several weeks ago. Can't believe I missed my chance to buy under 1 dollar after all these years! It's killing me.
