I bought coins, they dropped by 25-30% and are hanging around with a volatility of 10%. As a result, I can't average down according to your scheme, nor can I sell.

And yes, there is a difference between spot trading and futures trading, and it's not just about leverage. Spot trading can be more related to investing and long-term (similar to buying real estate). By the way, real estate also decreases in value sometimes... And if real estate can be rented out, then spot can be deposited in Earn for interest. Futures are traded short-term, ideally up to 5 months when entering a trade and 1 hour when analyzing the trend.
