RE: I think you have to be a good psychic to be able to make good decisions on when to take profits on gold and crypto investment.

Think about it this way: If people generally timed the market perfectly being in massive profit, then who would pay for those profits? Practically everyone times their trades imperfectly and for most traders trading is a loss-making activity. Only a small minority of highly skilled traders can turn a profit consistently. For most people, it's a casino where the odds of losing are much greater than the odds of winning.

It comes down to knowing or understanding what most other traders don't. If you only buy every four years in a bear market and sell only when the general cryptocurrency market has gone parabolic like in January 2014, January 2018 and maybe December 2021/January 2022 etc., you can profit relatively easily. That's because most people who buy cryptocurrencies have no such long-term plans or awareness of what moves the market, which is the Bitcoin mining reward halving every four years.
