If you invested in a AllTimeHigh( ATH ), do not panic, it means that you lost a better oportunity of gains, thats all, nothing else. Your investment will be back in matter of days.
The Market Cap lost approx 170Bi in one day, this means Whales control the market, and a lot of people took profits by Stop Loss(SL), also, the Nonsense-investors that make decisions based on fear and greed, those are the first ones to follow trends, or , they will just follow.
I recommend you keep an eye on Market Cap.
*BITCOIN MARKET CAP DOUBLED FROM DECEMBER TO JANUARY* - SUDDENTLY, THE PRICE DOUBLED. LOOK FOR THE MARKET CAP! KEEP AN EYE ON IT.
Talking about market cap, yesterday BTC was 700Bi and now it is 611,4Bi. Which means, there is still a plenty of corporate money inside the market, to summerize, we're still going up.
