The value of bitcoin is going down due to the news of google about banning cryptocurrency related ads and ICO. But not only that Twitter and instagram according to some articles are also making those actions. Though it is unverified information but it is making a stir on the market thus have played a role on the drop of bitcoins value. But thanks to the news on G20 that says they are going to tackle about the benefits of cryptocurrency, bitcoin has recovered its value and hopefully to climb up more.
Besides that, FUDers are grabbing this opportunity to spread more fake news(although google banning crypto ads is a fact). Panic sellers also contributes to the price's bearish trend. As a bitcoin user, I think it is only okay for me even if price of btc goes down today. It will just mean that we are weeding out the weak hands and market will become healthier, it will also be a good opportunity to rebuy after selling at the peak or near the peak.
Maybe because of the fake news that is spreading. Like banning of crypto, btc etc. But it is still okay. The price pump again. Just wait.
