If you invest in high volatility asset, you need to accept the price can going up and going down for 10% in a day, 10% is also normal.

Yeah that's what art investors have been doing for years i mean we should be considering every single dip as a buy opportunity instead of cribbing and panicking about the dip which will lead us to incorrect decisions like panic selling. Mostly people who invest for short term tends to do this mistake and end up losing on profit by panic selling. People should realise Bitcoin is not gold to have a stable growth it can be extremely volatile as well.
