Excellent post and for all those reasons you mentioned are why I am invested. I also agree with your assessment on the upcoming presentation especially after the EU PR. I wish I had more money to invest.
As I said before, I am adding a little each month when I get my Disability check. After the RS of ACTC to OCATA my average was $10.00 a share, I am now down to $9.00 a share and as long as OCAT stays in the low $6.00 a share range, I will keep adding at the beginning of the month to get my share price down and build my shares back up ! :-)
