today bitcoin has experienced a significant price decline. almost 20% of the bitcoin price drops. if we look at the past bitcoin ever dropped and started to rise again. I think this is bitcoin speculation to sell bitcoin so bitcoin price is down .. i'm sure bitcoin price will go up and back to highest point. today's events are often associated with chinese news prohibiting bitcoin .. whether it's a big impact on bitcoin or not. I think the step I should take is to hold bitcoin for a long time. until this incident is over.
