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
m/2018/02/02/apple-co-founder-steve-wozniak-on-selling-bitcoin.html]sold his bitcoin because riding the roller coaster stressed him out.How do you manage any possible stress coming from Bitcoin's volatility?
I have one question, why cant we wait for the recovery of Bitcoin or any other major currency and do things that cause stress (sell at an unprofitable price)? Do you not believe enough that the coin will be above the price mark at which you bought it?
Different people, different situations, different choices, different reasons, it's not that we can't wait for the recovery of the market, the reason is that we have needs in life, we have obligations and responsibilities, we invested our money in something and took the risk to earn money, but we can't always be sure if it is going to give us positive outcome or the other way around. If you are in a pinch situation, your son needed the money for his operation to live, will you wait for the market recovery in exchange of your son's life? I don't think so.
though there are still other ways if we want to save our cryptocurrency, like borrowing fiat to our families and friends and you'll pay them once the market became bullish.
