Never buying in the first place is the best way to avoid losses. Not selling when you're down doesn't avoid the loss, it just keeps the potential to earn it back open. People confuse this all the time. Bitcoin is an asset. The minute it depreciates in value, you have lost the money. If you don't sell, you could get it back, but you could also lose more. Bitcoin is speculative and very risky. You cannot avoid risk of loss by buying and never selling. Refusing to recognize this fact is to live in denial of reality. Might make you feel better, but that doesn't make it correct. If you're worried about losing money, don't buy BTC in the first place. That's the best (and only) way to avoid losses.
