I agree with your thinking, because at this time the market has started to slowly increase and will continue to increase very high, so of course there is a high possibility that the next bull run could occur before the end of 2021 and I'm sure that the price of Bitcoin can reach at least $100k if the next bull run does happen.
From the improvements seen so far, Bitcoin has only been able to break through a new ATH at $65K and there is no sign of going up to $100K by the end of this year, but for a few more years I think it's still very likely to happen to Bitcoin.
