After 50% of decline and that "everyone" (say we hear them when the BITCOIN loses 25% as each time) shouted at the victory of the burst of the bubble, I estimate that buyer timing is very short term for the moment, with small goals.
Be careful not to be in buy and hold on the entire position, because the downside risk continues in the absence of good news on the bitcoin and all the regulation of crypto in China + South Korea .
So I place a very tight stop to BE to take position on a new wick under 8 000 € or lower.
