Yeah I think salt has big potential. The main problem I think it faces is if say someone put a 1btc collateral loan down and the price was 15k at the time. Let's say they got a 10k loan from that then the BTC price dips to 9k. It would be economically beneficial if the borrower just used the loan to buy BTC and not pay the loan back as they would increase there BTC holdings. Obviously this depends alot on salts max loan based on market price so they could just lower the max loan to help overcome this. I'm not sure what there max loan is as a percentage of colateral but was just thinking in this volatile market that certainly could happen.
That being said I'm bullish on salt as I feel eventually the spare tokens not sold on the platform will go into the platform as it's cheaper for the borrower to do that and the supply on exchanges will go down until the price is just slightly below that of the platforms (a long term price move).
