There's 7500 PCL, 18,000 CoinLion & 52,000 Zebi I can transfer (4.7 Eth ~)
Edit: Also 1.25m BAX, although not transferrable yet but we can arrange if you prefer
Im only familiar with PCL and 7k is much too small for collatoral purposes.
I may look into the other options you present but for now i will pass. I wish you luck on your loan
What else would you consider?
