It is the most popular tool among home and hobby miners for calculating their chances against the network's current hashrate, to see their expected chances and possible earnings. It is referenced in hundreds of YouTube videos.

bch.ee is a Bitcoin Cash mining pool that rewards the block finder with a 1 BCH bonus on top of proportional payouts. Built on open-source mining software, it supports any SHA-256 hardware and operates with full-round share accounting. Demonstrates not just an engineering mindset, but a product and business mindset as well: the pool has grown an active community of more than 100 users. Demonstrates the ability to pick up a new stack quickly and ship production-level software fast: the pool is built on C/C++, a stack I had no prior experience with before building it. Has already distributed 11 BCH blocks to its users (more than 34.3 BCH, around 10,000 EUR as of October 2026).
