If OP is still hodling and continues to do so for the next decade he'll be the last one to laugh.
But why not trade and increase your position doing so, if you know the ultimate movement is up, you can trade with a great advantage, seams much more sane than holding few coins for a decade.
If everyone was to think the same and hold and go away until 2025, the trending would actually decrease, unless the same persons wouldnt continue buying for that period.
