i know most of the people worrying about cryptocurrencies in 2018 because BTC price dropping continuously since january. but experts in this field know this is not a new thing and this is a normal fluctuation of crypto market. personally, i believe there was a hype in DEC 2017 due to newcomers.it overshoot ed and came back to the level of 6000. I hope this should be stabilized around 10000 soon and hope some hike around nov_dec of this year
