Why some people telling that bitcoin price will crash after hitting $10000?.
because most of them are butt hurt that they sold bitcoin too soon and now are missing out on the rise. so they wish it crashes so they can see the price they sold at and then buy back.Yeah you are right some of the people want to decrease the bitcoin price and to get back their sold bitcoins.
But I don't think price will crash there maybe ups and downs in the bitcoin price but it is normal in bitcoin.So don't sell your bitcoin if the price falls.
I hope the bitcoin price will hit $20000 in 2018.
