Business: Bitcoin: smallest unit

Self-tutoring about cryptocurrencies: the tutor mentions the smallest unit of bitcoin currently defined.

With a bitcoin worth perhaps $75K, how can you buy ordinary things with it? By using subdivisions of it, of course.

The smallest bitcoin unit, so far, is the satoshi: there are 100 million satoshi to 1 bitcoin. If a bitcoin is around $75K, a satoshi is worth about $0.00075, or about 0.075 cents.
