I think that the market fluctuation is caused not by small investors, who, when the market is so stable, buy it. But big investors, who want to buy even cheaper, can influence the market and thus cause market fluctuations. Right now we're pretty low. It's time to buy something into HODL tactics. Virtually all coins this year have fallen significantly and are still looking for the bottom. Bitcoin is still holding, and if it's over $ 6,000, it could eventually end the downtrend. I'm holding coins and not selling in fear that the price will go down. The answer to the question is difficult if you did not sell at the beginning of the year, now i would not sell.
Without the small guys chipping in the waves would be much smaller. Sure, the drops may be initiated by those big investors, but it's full force shows when those small guys start to panic. There's really not that many big investors out there and many of them don't even trade. Most of the wealthiest Bitcoiners are holders.
Is holding a good idea? If you did not sell and the market is down by 70%, like it is now, think about what you can gain and lose and what are your chances.
After a 70% fall and 8 months of bear market the chances of a bounce back are much greater, and even if it were to go down, how much would it be? Another 5%? While going up 10% would still mean that it's trading with 60% discount. I like the odds.
