What I got here is a very simple answer just to compare investing and trading.
Investing is when you buy someting like bitcoin or altcoin and then let it be frozen for long term to make more profit in a long run.
While trading is when you buy an item then sell it in short amount of time even if the profit is not that big.
Investing = risking what you can afford to loss if program run away scamming you Trading = believing yourself and putting your skill to earn some good profit with what you have in your hand.
Because of supply and demand, it is simple as that, if a lot of people starts to invest in bitcoin, the price will go up, if they all sell, the price will inmediately go down at that moment, it is exactly what it is happening right now (going down, like hell, lmao)
Yesterday you said you have 3.5 ETH. Now there is only 2.7 ETH. And where is the VIDEO? You are not willing to post an ETH ADDRESS. Their have to be an ETH ADDRESS, where everyone can see how much ETH you have. You have proved that this is SCAM.
