Although I like the Tezos network and I have participated in testnet on many lending platforms before, I had a lot of problems with this testnet. First of all, faucet is problematic.. Whatever I did, I couldn't obtain uUSD and uBTC.. It is more useful for the testnet to reach more testnet users, if faucet is on the platform. You can reach a lot of testnet users..other than that, when I go to the "supply" part and then to the borrow part, I get the warning that I need to make some supply before I do the borrow (although I did supply). If the problem was due to the collateral being turned off, I could not find where to activate the collateral. Therefore, I could not complete the testnet (I could not use borrow, repay and withdraw), whereas I spent a lot of effort even to reach the testnet tokens.
