It is really possible that Bitcoin price will go lower than 6k. As we can observe the market right now, it experience a rough road. Tight competition in the market is the one reason why Bitcoin is struggling to breakthrough. Bitcoin's price is low for the past weeks and if this will continue the market price will become lower. But I trusted Bitcoin that it will surpass the challenges it is facing right now. It has surpassed the same challenge years ago and still continue to shine among coins in the market. Let's be optimistic and continue to support Bitcoin and the market.
