I sold 80% of my shares during the height of the share value then I reinvested at post $2 as I didn't need the extra cash.
2 reasons; I realised I was going to pay too much capital gains tax and the other was I didn't need the extra cash sitting in the bank. I may have messed up but I know I have invested in a very exciting tech (2015).
My guess is BRN is trying to close multiple deals with phone company and other giants....only guess but if they close a deal with say Samsung???...we don't need revenue for me to cash in. I will sell to those out to those longer term investment houses.
I have been in too long (about 6-7years) and I need to move on.
But for me; the investment has been a good one but I am out of investment endurance a what was a very speculative stock to begin with.
