1) Start small (get a #bitaxe or tiny miner)

2) Mine for practical uses cases (heat, industrial use, making otherwise wasted electricity practical)

3) Cloud mining is (almost) 100% a scam - if you don't have a serial number for a miner that you can eventually custody...you're not mining.

4) Mining has a cycle just like #Bitcoin - the best time to mine is when BTC is "dead" and hashrate is at historical lows.
