While I agree that this is not the end of bitcoin and that drops are yet to be expected, I also think that visualising the last >10% drop in the context of the overall bitcoin history in the range of 0-20k as a prove that it is not significant is a kind of a manipulation. It was a big drop. There is no denying that.
believe me this is one of the games of big investors to shake up prices by creating panic at small traders, actually going up and down from bitcoin is very normal, we also see many times the price jump, so we must always believe that bitcoin will be stable and rising prices are temporary, for traders do not panic.
I am sure the Bitcoin will not end up here. Bitcoin has the ability to continue to grow and produce more expensive price to bring it into the main Cryptocurrency coins today and into the future. so relying on Bitcoin will be able to generate more profits.
