I have coins I have locked up in my hardware wallet, let it be there from now till 5years.
That's a good strategy. However, the key to HODL is knowing when to SODL.
Since you never know what the market will do, my strategy is never to HODL everything. I'm holding a portion of my investment and selling another portion, when the price is right, so I can hedge my investment. It reduces the risk of losing everything.
