What is the difference between trading and gambling?

Some say there is no difference; trading has techniques, and gambling has techniques as well, one bets on price fluctuations, and the other bets on size.

But I don't think so.

I believe the difference between trading and gambling is that in gambling, you must place a bet before you can draw cards, but in trading, you place a bet only after seeing the cards, and you can also choose not to bet.

Trading is more akin to running a store or engaging in business activities, which are all based on thorough investigation, investing a portion of the principal to take risks, which is clearly fundamentally different from gambling.$BTC $ETH
