At the halving - $10,000 to $12,000.
Late 2021 - $70,000 to $100,000.
Really agree with you mate, most expert prediction for bitcoin in the late of 2021 will above $50k. Just remember in the previous halving, like 2016. Lower supply will increase the price. And now maybe will be a cheapest price of bitcoin. And if we back to 2009, when bitcoin price only $1, who will believe the price will increase x20.000i n 8 years?. 😁
