if you are someone like Warren Buffet or Elon Musk or any market makers who bought BTC under 10k and sold it 40k, 50k, or even 69k right ,think it with your self , why shouldn't buy again at 10k ???
BTC after every ATH takes 1 year rest and correct it's price more that 80% and it's worth to buy again ,guys just be patient and every moment that u see price about 10k go all in BTC
