You are a clever boy and should not ask more, but conclude yourself, that my X BTC wich I kept in scrypt.cc produced more interest, withdrawen since 31 May 2015
Why, thank you! 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?
Just out of curiosity - why don't you want me to ask more? Help a clever boy out here - help me understand your superior logic!
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
