I'll admit that I still check BTC's price as frequent as when I first got into cryptocurrencies, but I sort of feel "numb" to the volatility. Bitcoin crashes by $5k? Meh. Alright. Time and experience in the blockchain ecosystem made me used to the huge price swings I guess.
Normally, time and experience will always help. Most of us have been there in the past and those who really never had that problem were those who invested when it really does not have much value and no serious fluctuation since there was no market for it anyway and all they had was hope and belief that one day, things would get better. However, if those who are buying now can also have that mindset, they really would not bother about now, and they would rather focus more on the future.
If you have invested your money into bitcoin and that you have a plan of holding those bitcoins for longer term, then there is no such need to check the market value of the bitcoin on daily basis. It is a good thing to know the market value of the coin in which you have invested but there is no point of checking it after few minutes. You just need to stay calm even if the market value is falling.
