Most people don't make it big because they can't open their mind and be critical in doing analysis.
Most people don't make it big because THEY BET AGAINST NEW TECH.
Just as those people who bet against Henry Ford.
Just as those people who bet against Internet.
Just as those people who bet against Computer.
Just as those people who bet against Smartphone.
If you don't understand the technology, don't touch it, don't bet against it.
Shorting will give you much lesser gain than betting for it and if that thing goes big.
The richest man in the world are Bill Gates, Jeff Bezos and these are investors, not short sellers. Soon, Satoshi Nakamoto will be the richest man in the world.
If you bought Microsoft Share in 1990 WITH MONEY YOU CAN AFFORD TO LOST. You already made 100x THAT AMOUNT OF MONEY.
IF YOU CAN AFFORD TO LOSE 100 BUCKS, YOU WILL BE MAKING 10000 BUCKS
Replace this with every new tech. Apple , Tesla , Nvidia and so forth. You will see the same parallel forever. Crypto and Blockchain may be the last opportunities. Unfortunately, a lot of people will be SHORTING crypto just as those who shorted Microsoft in 90's, Apple in 2007, Nvidia before 2015 and currently Tesla .
So, now you already know the answer and reasons why you failed in life and failed miserable.
