Many people say that with Ethereum at 1800, they should buy more. What I want to say is that you need to see if it's at the bottom. If you want to buy more at 4000, no one will stop you. You may have a lot of profit, but if you buy at 1800 and it drops to zero, is that possible? The profit potential is so large when it goes up, but the fear is that it doesn't drop. If it drops, it's an opportunity.
