The worst thing you can do in this cycle is try to squeeze every last dollar out of the market.
No one will be able to accurately determine the peak time.
Therefore, choose levels now and stick to the plan when the time comes (good thing you should have set goals a long time ago).
Every cycle people say that they will get out of the market as soon as they get their fortune. And every cycle the same people become greedier and greedier... and in the end they give most of the profit back to the market. The most that they have left are screenshots of how cool the portfolio of such and such a number of such and such a year looked.
If you earn life-changing money, use it to really change your life.
Buy a house. Make your dream come true. Buy an engagement ring. Retire your parents early.
Don't go round and round so that you don't spend the next 4 years thinking about what and how it could be.
But also remember: never sell all your Bitcoins :)
