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?
I don't agree for what you said to not look back and move forward. Its hard to move on if you experience huge losses in your folio. And looking back means you are reminded not to commit the same mistake.
