I think a bull run can happen at any time, it doesn't matter that the current price looks lower than before, but as long as the whales are raging it will make it easy for the price to skyrocket, as happened before, in 2017 the price started the year under $ 1000 but the end of the year once touched $ 19k.
It's a cycle though, bulls and bear market, so in any case there will be a bull run, a final catalyst will be the block halving which is still still a year from now. We can look at bitcoin's previous history, like you have said, in 2017, it was under $1k and then goes off to $19k, that is a huge growth. But you can really compare it's massive growth every bull cycle though, because it's going to be very difficult to hit that multiplier. The growth will somewhat slow down. That's why the prediction might be a conservative 2x so maybe $120k in the next bull run, not that bad assuming we all have save a lot of bitcoin in this period or bear market.
