It is possible. Bitcoin halving brings positivity to the market, we don't know when the market will start to move upward but base on how we all experienced from the previous halving, it helps to lift the value of bitcoin.
Reaching new all time high is always there, it might happen or maybe it shouldn't. We really can't say for now, but the possibikity is always there.
Agree, the halving event makes bitcoin less, its value is forced to increase to accommodate this scarcity, and when the bridge to connect altcoins becomes more expensive, items around will also get a similar effect, environment and favorable conditions, altcoin will have new value milestones. But will it be the highest milestones in history or is it just ordinary milestones, even the worst ones? We cannot predict this situation, the scope and probable things are very vast, waiting is the only way to see the next page of this story, judgments are just spiritual help
