I think one of the factors that can affect the bitcoin price is bad news or FUD's that can holders sell their bitcoin because they think that the price of bitcoin will drop and the other factor is there are some group of a pump and dump that can manipulate the value of bitcoin and the other thing is there are many scammers out there that use bitcoin as their presentation that is why people didn't trust bitcoin because of this reason.
that's right what you say. and if I think also with the many negative issues that are about bitcoin then it could affect the value of bitcoin as well. therefore we all bitcoin users must support bitcoin continue so that its value can go up and not be considered bitcoin negative hold
