Currently BTC is close to the $ 20k ATH price, but I think FOMO is still very low, much lower than December 2017, so maybe BTC will break ATH in the next few days. Because BTC currently has only one resistance level of $ 20k ahead.
On the contrary, I think FOMO is very high these days, much higher than it was in 2017. We were just $2,000 short of reaching $20,000 just a day or two ago. During these same days back in 2017, the price of Bitcoin was even lower than $10,000, just around $7,000 plus. So that means we are earlier now. FOMO is felt really strong. We could enter $20,000 before December this year.
