I Should definitely sell. one dollar in your pocket is worth more than $100 on paper, unrealized.
Remember these are Pink Sheet Stocks. Don't fall in love.
Suggestion: sell some to get back all your capital or most of it and let the rest invested, if it goes up, u win, if it goes down, you don't lose much (or nothing at all).
Don't be greedy!
Be cautious, You can always invest somewhere else
