pooya87, if this account "Phemex_official" would be the official account of Phemex (it is not), I would declare you the winner!

This giveaway is not about declaring someone a winner, the winner will be the one who gets access to the bitcoins.
Since no one has solved this puzzle it only proves the complexity of itself... Phemex already gives some hints:
Without further ado, here are some clarification and hints to help you solve the puzzle:
The first 21-digit prime found in consecutive digits of e is: 957496696762772407663
The private key you derive from Satoshis portrait is a big integer, not Wallet Import Format (WIF)
The filename of the picture is irrelevant
The next step involves converting some words from the portrait, without I/O, into a 27-digit number
Go back to step 4) again if you cant figure it out
Even with those hints get 27-digit number is a hard task... So, Happy puzzling.
