risk - bbp & 19c

So I have a question for people,

Is the risk with BBP worth it from here if the potential gain is just over double your money? (19c)

Originally I thought that it was worth the risk if BBP was going to achieve anything near NTA, but i am not sure if it is worth the risk for only double the money. I have others in my portfolio that are a lot safer and have achieved double gain.

Looking at it differently, Beppa is probably in a less, or equal risky position, yet has a far greater potential gain.

Additionally, is 19c a reasonable figure? Or if you think it is too low what do you think it might be?

Thoughts?
