One bad day when Bitcoin fell from $42,000 to $32,000 and possibly even more. Bitcoin's capitalization has decreased very quickly. We hope good things return soon and Altcoins will rise.
It seems bitcoin started to recover but it will not bounce back again to the 30k again as the chart looks still bearish at this moment. I do believe if bitcoin are looking for the best rate to did the stabilization for its price. It says that bitcoin has the possibility to get another dump again. Maybe 20k - 30k range will be the new bottom floor for bitcoin.
It's quite difficult for altcoin to rise against bitcoin. Altcoins gets deeper correction than bitcoin.
