Since as you said that you have a proof that chips.gg has stole your $2k you better post a proper scam accusation against them in this section https://bitcointalk.org/index.php?board=83.0

You will get more better attention if you post that there since provably your case might be forgotten by people or even them especially if there would be lots of discussion will be posted in their thread.

But as other said chips.gg is somehow a big casino and maybe better for now to contact their support to know if they can do something to return your funds.
