Speaking about halving effect? Its always been bullish but we cant be sure on what would be the dates in regarding on this one
but im not really that too optimistic because we know that history could neither happen once again or would be seeing different this time.
Halving creates fomo because there are less Bitcoin being put into circulation after each block reward it is a basic mathematical idea that it will increase in price because of there being more demand for some thing that gets lesser as time goes on. It will go up after the halving but it is hard to put a time frame on when it will increase. FOMO can take a while to happen.
FOMO plays a part, however the price increase takes some time as the miners begins to adjust to this new reality of getting less bitcoin with each block they mine, so miners are the ones which set a floor as they are not willing to sell their coins for a loss, and this floor keeps getting higher as they need to remain profitable to keep mining bitcoin, eventually traders and investors catch up and this is what causes the slow growth we see after the halving.
