To trade, you must first understand: Everything that can be speculated is valuable.
For example: gold, real estate, cryptocurrency, tulips...
However, as an individual, you need to know that only things with bull and bear cycles have long-term value. For example, tulips, one wave ends, and from then on they are just a bunch of flowers...
The bull and bear cycle of gold is about 5 years; real estate is about 30 years; cryptocurrency is about 3-4 years, and there is a bull market every year.
As a person, you need to make a choice that suits you according to your own situation (skills, age, size...).
Time cost is also a cost. When you are in your seventies or eighties, even if you have a fortune, everything is meaningless.
Good luck to all of us
