1. I joined Learn2Trade, where they provide 5 suggestions per day, on whether to BUY or SELL.
2. I understand how to BUY and wait for the price to go up.
But I don't understand how you make money on SELL.
For example, let's say I believe BTC will go down. So I BUY BTC. And then I wait for it to go down and then SELL.
Don't I lose money?
You can only do it if you're with futures trading where you can be profitable when the market is down trend. You can't do it in spot because if you do you will lose your money only if you sell it below your buying price. However, if you're going to trade with futures, have enough knowledge but still a newbie, I recommend to use a small leverage only. And please bear in mind to use Isolated mode instead of cross margin mode to safeguard your remaining funds if ever the price drastically going down and forgot to put a stop loss.
