Investors already know about the halving, so their mood is already revived and priced into the BitCoin market. There will be ZERO surprise, or zero change in mood the day the halving actually happens, everyone knew exactly what was coming and was already in that state of mind...
You must be wrong, no investor will be waiting until the day where halving is going to take place. They will react well in advance like they will rush before some big investors will enter. This is the exact cause of FOMO. I agree that halving in bitcoin ecosystem is a well expected event hence there will be no surplices but that doesn't mean everyone will keep doing what they are already doing.
Yes, everyone who are aware of bitcoin halving, definitely think about some investments with the expectation of some ten fold returns because in the past every bitcoin halving has produced that much big returns. So unlike you have mentioned, halving will not be ignored by investors.
Talking about 10 folds here wont really be possible nowadays if we do base up the intensity of volatileness of the market of the past years.It isnt similar wayback on 2017 where we can shoot up even thousands but this one
is only for alts but for btc when 2-3x the price would be somewhat realistic rather than hoping for 100k prices or even higher which is too much in a short period of time. Halving event is indeed an important one and
its really impossible for it not to get some consideration on accumulating coins before it do happen but most people will surely sell off into that particular day.
