Just update here - the borrower just send me 200k Chesscoin as collateral
Though I'm not an expert, I think he sent the fake collateral

Here's the tx id:
https://etherscan.io/tx/0xc4ef616f0ce5d25e0ee7cc37a1077921197cd4945e8d3f9288f7fb472cd95c46

Again, I'm not an expert, but if anyone could verify it and let me know if it's real or fake
It'd be much appreciated, thanks in advance.
