Well the dev trough at 3c earns 85k in 2 months, at 6c it's 170k. I would expect that GAB to provide the remaining 30k for bitvavo.
42.5k a month is gg, at 6c 85k is super gg. I earn a good income for my age, slighly under 4k as a mechanical engineer, most of my friends are ranging from 2.5 to 3.5k a month.
