I am not a financial advisor and this is not advice. Consult a professional. First, completely ignore anyone who says “I think it will go <up|down>, so you should…” or “Sell when the time is right.” Trying to time a momentum-driven investment and failing is what got you in to this problem. The first step is acknowledging that this was a dumb thing to do and that you don’t have any more skills at reading this market than anyone else (and some random commenter sure doesn’t). Second, that matters because it lets you reach this conclusion: your current portfolio value is all that matters. You can’t undo the losses, but you have complete control of what happens to the remaining principal. You bought a very expensive lottery ticket, it didn’t win, and now all you can do is decide whether to buy a second very expensive lottery ticket (hold) or learn from your mistake and do something smarter, like actually investing this. Ask whether, today, you can afford to have X% of your investable assets in a single asset. Based on your post, it sounds like X is a large number, maybe even over 50%. Assuming you can't afford it, start here: https://www.fidelity.com/viewpoints/guide-to-diversification https://www.fidelity.com/viewpoints/guide-to-diversification Note that you don't need a plan in order to liquidate and hold cash. Don't get hung up on not having a plan; cash is a fine asset. The other reason acknowledging to yourself that you can’t time the market matters is that, if you sell and then it goes back up, you shouldn’t feel any worse about it than, say, if Google’s stock or some random smallcap stock went way up and you didnt own it. You didn’t “miss out” on anything, you opted for diversification and predictability - that is, market-average returns - ahead of a lottery ticket. (ObDisc: None of this is a commentary on cryptocurrencies, good or bad, only on taking outsized risks with money one can’t afford to lose without caring. OP’s remaining principal obviously is not that or s/he wouldn’t be here.) Third, after dealing with the time-sensitive stuff, consider seeing a therapist to see whether some underlying issue led you to take this much risk. Not at all a value judgment, but taking huge risks with money you can’t afford to lose may be a manifestation of self-destructive tendencies or at least a sign that it’s time to make some changes in your normal life. Good luck. PS in case it makes you feel a little better: many people have spent a larger percentage of their assets self-funding a startup than you lost – and also gave up years of their life and opportunity cost to do it. Life goes on. The important part is to incorporate what you've learned into future decisions (starting now), and to assess what led you to do this in the first place.
