I told you, now I keep X and withdraw the benefits

Compute (X + X * (1.017^(5/9/2015-31/5/2015) - 1) - 20) / X
and given X, you will know what is my benefice untill today

And my question was - and is -
why don't you withdraw it all? Given that you acknowledge that you've been ripped off for 20 BTC already, I want to understand why you keep
any money at scrypt.cc. Is it because you can't withdraw it? Is it because you don't understand the difference between realised and unrealised profits? Is it because you're happy to gamble? Or is it some other reason I've not considered?
I don't really care what your "benefice untill today" is - what I want to know is why you still have money invested in scrypt.cc, given the 20 BTC rip-off you experienced.
Here's what I asked you in my last post, I've repeated it here so you can answer the question I'm asking, and not imaginary questions about "benefice":
So, in summary, you still have BTC "invested" at scrypt.cc, and - despite already having been ripped off for 20 BTC - you're quite happy to keep the money invested there because it's "just" (unrealised) profit? Is that a fair assessment of your situation?
...and the same question, from the post before that one:
Were you unable to withdrawal all of your "investment", and left with no choice but to sit it out until you could withdrawal everything?
