Say you bought it for $6500 (not the lowest in Nov). That would give you about 2.53 BTC. About $28k. My point it, markets are all about timing. You can pick and choose your dates. Stock market is a risk, albeit a safer one than btc. But I still think you should have a small position in it.
This is false and dangerous advice. study after study after study has shown it's "time, not timing" when it comes to successful investing.
JP Morgan did a recent study of this. if an investor stayed fully invested in the S&P 500 from 1993 to 2013 (5,200 trading days!), they would've had a 9.2% annualized return.
However, if trying to time the market resulted in them missing just the ten best days during that same period, then those annualized returns would collapse to 5.4%. Those 10 days grew their returns by 50%!.
The best 60 days (only 1% of all trading days) accounted for the entire growth of their portfolio.
Do you know when those days are coming? if you did, you'd be on a yacht in southern France. The best financial professionals don't know when those 10 (or 60) days are. You cannot beat the market long-term by timing.
