I lost my shirt and sold out at 10 which was very very unusual for me. I hate to lose so I normally let the stock sit in my accounts and then gradually add to them on a quarterly basis. A couple of years ago I bought some Tril (5K) for $0.50 and then it dropped considerably, I then spent a year adding. My last buy was at $0.17. And 11 months later sold 70k shares for $1.4 mil,
Currently have a ton of Iova where my last buy was at $3.75 6 months ago which now is $11. RGLS went from 50cents to $2,50 in 5 months.
If you believe in it put it away and add when you can.
