Keep in mind Very Volatile as all crypto is, so buy and hold but not all in to keep safe if you bought 2 ETH at $2000 and Closed 1 of your ETH at 4000 you have 1 ETH for Free, So the real secret here is Management, any Equity that you have that doubled Sell half ay high and you have half for Free,, which means you are Risk Free forever and just leave it alone.
