If you would lend or borrow crypto on a collateral lending platform which repayment model would you choose?

Just to clarify:

1) KISS strategy - keeping it simple is very important for every platform when it comes to fluent operations. The platform will be easier to understand and follow.
The borrower shall lose the pledge if the percent of loan value versus collateral value exceeds 95% minus repayments ( motivation for the borrower to repay the loan on as many repayments as he/she likes whenever he/she likes). There might be additional trust rating for borrowers sending payments regularly. The only cons - it might happen that long term loans are repaid at the end(again, this is balanced by the loan/collateral ratio) , without intermediate repayments, the platform could put a maximum loan period 6 months or so.

2) Multiple payments - btcjam style. Borrowers takes the loan(including long term ones) and are obligated to repay the loan on a predefined payment periods.

Feel free to comment on those models so i can adjust the poll if necessary.
