The market is falling is it the affect of the upcoming segwit? Or just a normal move in the market in which is the up and down of the price?? Is it ok to hold bitcoins in the exchanger? Can you help me???
segwit may be the main reason for this price movement,It is not safe to keep your coins on an exchange on 1st Aug (or even a few days after that). See this:
