It seem it was another pump and dump session by some smart whales. We had an addition of about 12 billion USD by morning and the market bled by noon. It does not however mean we still cannot have it otherwise,
We unexpectedly experiencing dumps today and turning back into $3,700 from that high of $4,100. We don't know if it is for whales doings since we can't even prove it but for sure there is a reason behind for these.
This is the reason that we can't expect bull run early this year since looking the market doesn't have strong resistance. This huge dumps of BTC price today will affect the entire market.
