The arithmetic
The range for puzzle #150 contains 7.13 × 1044 private keys. A modern eight-core laptop running this solver checks on the order of four million keys per second, so an exhaustive sweep would take about 5..6 × 1020 years. Searching randomly instead of in order does not change that expectation — it only changes which unlucky order you fail in.
