so how did you lose 60k? did you sell your coins? if not then you can still earn it back. the price drops but you still have the same amount of token. but if you sell it due to panic then better research next time. learn from your mistakes so you won't repeat it again.
Your advice is meaningless. Traders also an earn under bad market coinditions like bear market,flash crash. For example,if this guy sold his assets on downtrend later he can buy back same amount of token for less price. Difference will be profit for smart trader.
