In my almost four years of getting involved (just an ordinary holder and part-time trader, nothing so great actually), I am so sure that Bitcoin can be a major source of stress especially if you bought them at a higher price and then the price made some slide. Now, I am not saying that it is Bitcoin's fault because stress in the first place depends a lot on our perception and how we are managing it. But definitely, we can categorize as a stressor at some degree.
On the other hand, Bitcoin can also be the source of "happiness" especially when the coin is having a great time jumping upwards. Certainly, there can be euphoria if in 2020 Bitcoin can go higher that its 2017 ATH. Bitcoin is known for extreme volatility and it can go from one side to the other in matter of hours and days.
No wonder that Steve Wozniak the Apple co-founder
sold his bitcoin because riding the roller coaster stressed him out.How do you manage any possible stress coming from Bitcoin's volatility?
After 2017 year and great times in cryptoworld for everyone it was hard to accept the fact, that lots of assets and enormous opportunities had been lost forever. And of course telling the truth it would be a real lie to tell that there were no stress after loosing in 2018, but ups and downs it is the life, not only in cryptocurrency world this rule works. So first of all it is the experience it's no doubt. And the main thing is your mental and physical health. It is the most fragile thing I think. If you remember about this no other thing will matter so much. Nothing will make you go mad. Without yourself no money or crypto will have any sense.
