In 2010, I didn't know about Bitcoin, and I'm sure many others hadn't heard of it either. Dwelling on past "hidden gems" often leads to regret, but it holds little meaning for the present and future.
You are absolutely right bud, holding unto miss opportunities in the past can be very detrimental for our future, though many usually fail to understand this.
Holding onto the past opportunities we missed brings regrets, and this regrets usually blinds us to the present opportunities that is steering at us, and if we fail to let go off the things of the past to enable us see and grab the present opportunities, we will discover that at the end of it all, we will still have even more missed opportunities to cry and regret over.
I've stopped thinking about the opportunities I missed in crypto, I rather put that energy in finding new opportunities in this present day, this helps me in the sense that, in the future again, I won't have to regret and cry again over missed opportunities.
As long as crypto is concerned, there are opportunities every where and everyday, but one need to be determined and focused, to see and grab them.
