It is true the volatility of bitcoin has gone down compared to the previous cycles, however this is bound to get even worse as times goes by and you will have to find a way to deal with this, in a way what you are going through sounds similar to the feelings those that practiced an extreme sport go through once they stop doing that activity, they feel their life to be kind of dull and they miss the old days in which they did all of that crazy stuff, and if I am honest with you there is not much you can do about it, as bitcoin is not going to change its behavior according to our needs and we are the ones that need to make the adjustments instead, however once the bull run starts and you see the profits coming it is likely you will forget about this for a time.
People can make mistakes, as mistakes are related to trading, it is possible sometimes, that due to a small mistake, there can be a huge loss, so it is a common thing. Also, bitcoin volatility is from the very start, but not only bitcoin every coin changes from time to time, it doesn't matter at which time someone has taken entry it will be changed. Analyzing all these things also creates some good vibes in the trading and helps the trader to go on.
As the bitcoin can't change for us we can change our strategies and we can do trading in some other ways so there will be smooth trading. Trading creates a massive impact on a trader if he has much knowledge about the trading.
