Every time I see the numbers 20k, 15k, 13k, I don't believe in that bitcoin price. But now bitcoin is already worth almost 19k and it only needs to drop 30% to reach 13k. I guess it's not as fantastic as it looked a month ago. Now we just have to hope the price doesn't fall even lower. Surprisingly, altcoins are not reacting much to bitcoin's continued fall right now.
