We should probably wait for another year for this resistance at $20k to be overcome, Bitcoin has tried to move beyond the price mentioned above several times and whenever it climbed to $19.8k or $19.6k the price dumped quickly as there are more selling pressure at that level. Though we had some good correction in regard to Bitcoin price and hope that the next bullish thread of Bitcoin brought us into the $20k+ zone after the 1qauter of 2021.
Another year? Are you kidding me, we are at around $19k right now and only 10% away from breaking well over any resistance and to be honest 10% is nothing in the crypto world that we should fear about.
I feel like we have a chance to actually take that $20k and be over it very soon, probably in December without waiting to be in 2021. However there is a good chance it could wait as well like you said, but not a year nonetheless, I fear that this could be something that will happen quicker than that, probably around late spring or early summer if we were to be too late for it.
This is why I am going to actually keep investing into bitcoin even to this day, because I know that without waiting for too long, I am going to make a profit. Even today someone who invest could make 10%+ profit in under 6 months which is still good for traditional markets.
