When you decide to invest in Bitcoin, you can either buy Bitcoin
directly dollar for dollar, or you can invest in mining machines
that unlock Bitcoin directly from the blockchain. Both options
allow the investor to own Bitcoin, but only mining gives the
investor ownership in a hard asset. Through mining the investor
hedges his bets, establishes a passive income stream, and invests
in Bitcoin.
Mining will often yield a higher return on investment than buying
Bitcoin directly.
