I believe there is no such thing as a bad market. It's all in how you use the market.

Red is a buyer's market. All coins are discounted! Short selling is feasible. Loans become good as now you don't have to pay back as much as you took out thanks to deflating coin prices.

Green is a seller's market. All coins are going up but might be overpriced so buy with caution. Those who bought during the red are now making money. Mining is profitable.
