That's why price went down to 1700$, PEOPLE STOPPED USING BITCOIN, because of the lack of credibility- namely slow transactions and high as fuck fees. After that price returned to ~2700$ ONLY because of speculations around Segwit2x. It's the only reason, bBitcoin is dying and u all know it.
The price went down because there were a lot of uncertainty about what would have after the fork and so is the reason there was a panic among traders and sold them off and it raised just like that within a day or two because we had a clear picture on what is going to happen and bitcoin is here to stay and i am interested to see how bitcoin cash will grow after its existence.
