I am a strong believer in HODL. I expected bitcoin volatility decreases as time goes by, I totally didn't expect such big price change in the past several days.
Is bitcoin volatility here to stay and not decrease?
The volitle price of bitcoin and other altcoins will not disappear and will remain the same in the future. And it is possible to increase it over time especially since many whales control it.
Therefore, holding is no longer advisable now, as the price of bitcoin and other altcoins is unpredictable.
