I like to distinguish investing from speculating. Investing is putting money into a business which actually makes money. Speculating is buying something because you think the price will go up.
investing is not just that. its putting money where you expect the business to make MORE money in the future. if they dont, you dont make money in the end.
When the stock/crypto goes up 100% people will gladly take their profits and go on with their lives, instead of waiting for even bigger profits.
When the stocks starts its fall towards 0 people will do incredible mental gymnastics, clinging to any shred of hope that things will turn around and they will revert their losses, so it takes them much more time to get out of the bad investment.
The only proven way to make a killing in crypto is to be physically prevented from losing it, trading it, or selling it for ten years.
