hi
i have try in the past to take a loan with collateral, but with no success
unfortunately there is no p2p lending service with collateral yet
now about
http://blog.btcjam.com/"Payment cycle options reduced
Four payments a month is just too many
and if you miss a payment, it could hurt your credit score. Our new monthly loans make repayment easy as it matches your schedule. Payments are only on a monthly basis only."
i always pay in these 3 loan per week never had an issue, all times pay days early or on the time.
If they want to help they can leave payment per week and 15 days. Some investors like to receive their payment per week or asap.
There is still people listing loans with payment cycle less than 1 month(every 3 days and weekly payment is still possible options) so btcjam hasent implemented the thing you mentioned that they posted on there blog the March 27, 2015.
