30 Days, but you can easily extend the loan for additional 30 day periods. Just burn 0.1% of the gTroop tokens you placed as collateral for each 30 day period you wish to extend. 

No. Your loan is secured by the asset backing per token not the current market price of the gTroop token.

No. You can keep extending the loan for as many 30 day periods as you like.

If you do not extend the loan nor pay back the loan, the gTroop tokens you placed as collateral will be burnt.

The asset backing per token helps protect you against being rugged. You can always borrow the amount of asset backing per gTroop share and simply not pay it back.

Rather then have token holders spend gas staking and unstaking their tokens, the funds that would otherwise go towards staking are used to (a) increase the asset backing per gTroop token, and (b) burn gTroop tokens. Both of these uses benefit all token holders equally and also may be more tax effective is many jurisdictions.

The Ape Pool is our secret sauce that we hope will drive the asset backing per gTroop token even higher. It's success should be measured by its impact on the asset backing per token.
