From so many points of views, Bitcoin (BTC) trading is investing with the aim of making profit and making gain,I have understood it purpose and it is vulnerable to it's stakers.for one to stake means he/she is ready to profit or lose.
Trading and investment are very different, trading is when you convert from one form of money to another, a good example is converting bitcoin to Fiat or converting Fiat to bitcoin, or converting one crypto to another, like converting USDT to bitcoin.
If you are investing, you will buy bitcoin and leae it to how in value over a long time like months to years.
Can you see how different both are.
