You are already in cryptocurrency and you should not regret it.
YES, the course is unstable. Sometimes there are mistakes, but do not look back. You will not change anything. It is better to assume that you made the right decision, even if you got a loss.
We need to move only forward, what do you think?
Looking back isnt really that bad yet those mistakes will really give you out some lessons that you can apply on your current state of trading.
Just not to focus on how you loss money but the lessons that it gives you are precious.
Those are stepping stones for you to be a better investor.
