6- Do I have to use a mining pool?

Typically, you do need to mine Bitcoin from a mining pool unless you are mining for a block like buying lottery tickets. The collected work of millions of machines allows small miners who could statistically never win a block, capture sats for their contribution. Atomic can share a list of vetted pools with you. If you are a business making large investments in Bitcoin, contact Atomic’s concierge desk and explore options that may or may not include mining pools.
