I remember putting money into Kiva around 2007, it was increments of $50 IIRC.

Unfortunately, I lost a job and the ability to work, spent 401k, went bankrupt and lost access to the email address to my Kiva account. It seems ironic as I no longer have even $5. I don’t really worry about money anymore with serious endocrinological, ophthalmological and neurological problems... sleeping 12 hours and awake for 60 hours might place small limitations on life.
