Of course, as many of us regreted not investing in 2013, but that´s life and some people are simply not ready to develop new areas for their money to work with them.
I even thought that I was late to invest on crypto's by late 2015-2016.
And the good thing is I decided to invest and I was never too late for it. They still have time and they were never too late for it. Regret today but learn tomorrow and start investing.
