most of cryptocurrency are red for now and down in USD terms,, especially bitcoin
at this moment bitcoin price down below 10K USD depends on coinmarketcap data
is this the best time to buy more bitcoin ?
buy, buy and buy. that's what I recommend to you in a bleeding market like today. collect altcoin and bitcoin belong to you as much and wait for your investment development at the end of 2018 the price will be pumped as high as possible, I am sure of it
