although it's downtrend, bitcoin is not danger and bitcoin will rise back in the future. once bitcoin is up, the other coins will follow and I think right now, the trend is trying to change and we are almost to see every coin getting increase. people that thinking bitcoin danger is only because they don't learn more about bitcoin and they are too afraid if they buy bitcoin right now, the price could down in any second and it will down too deep. but if they can learn about bitcoin and they have a passion to know more about bitcoin, they will not say that bitcoin is a danger.
Moreover, despite the decline, the current price is still much higher than in previous years. So true, this is not a threat of danger. If you want to be patient and analyze the market carefully then the profit can be obtained when the price rises.
