The best time to mine is during doom and gloom.  So when things are hot, take some earnings and set it aside.  Then create a continuity and contingency plan for when it does crash and rebound.
Furthermore, global crypto market capital is growing as time goes on.  Crypto is becoming an emerging market of tremendous growth and volatility.

Right now, I actually plan on investing in sustainable infrastructure for mining and hosting.  The plan will be for 5-25 years of operations and minimize any disruptions.
