Yes, that's the way to go; especially the first option – hodl. You can also do dollar cost averaging – DCA. That's; buy more as it drops to average out your loss. Understandably, I know that's a hard thing to do right now because most people are in a panic and it's obvious in the behaviour of the market. It takes an investor with a steel heart to buy at this moment that the market is reddish. This dip, I believe, will herald the alts season. We saw that happen in 2017 when Bitcoin started dipping in December of that year after hitting its ATH and the preceding month (that's January of 2018) alts began its rally into first quarters. I expect that to happen now if history were to repeat itself.
