I lost too much money due to this btc dip, What is the reason of this dip? Will it recover soon?
FUDers.

Whales are accumulating, just watch the trade amount. As soon as they got their fill, watch it skyrocket to a new ATH.
Remember the JPMorgan FUD late last year? They bought hundreds of millions worth of BTC at a discount shortly after that. Same is happening now, businesses are poised to use crypto and they are investing but at low price. With enough money, you can manipulate the market and make money off weak handed investors. Sad fact or life.
HODL!!!
I think ATH will come in much later. Right now the market is shedding off new scared investors and weaker hands from Asia.
The main reason for this dip is overblown market and rapid hammering by governments and media. I think a lot of new investors came in wishing to make quick money. On the other hand media and governments colluded to time all the FUD news in the last few weeks. While none of believe that this will be the end, I think we were ought to see a huge correction. If you are a new investor, the right time is either buy now or wait till Feb 6th to see what SEC and CFTC hearing says. Be ready for another dip if media exaggerates !!
