I am up almost £70k on a £200k holding. I am so glad I listened to some of the more reasoned folks on here. Will hold until it goes to £40. I must say the Nithin guy spouting this share going to £10, did make me nervous, otherwise would have put another £100k down.
I am up GBP40k on a GBP200k position. Was painful building up when it kept on going down during christmas, but Best investment I made in 2018. Holding on until it hits 5000 again.
