I think if bitcoin break the $6000, then bitcoin price can get lower and maybe $5000 is the lowest price. and if the price still going down and reach $1000, then we might be back to 2011-2013 again because in that time, bitcoin price is down too deep and it stays in that price level for a long time. and if this is really happening, then many people will get a huge loss especially for people who bought bitcoin at more than $5000 price level and they need to wait for a long time to see the price can back to that price level.
