Perhaps for those who have experience it before, I don't think that they might be concern about when the next halving will be.
Halvings are interesting by making more noise on media, then more new people know about Bitcoin, some of them join the market as newbies with new capital spends in the market. It's the most interesting effects from Bitcoin halvings and it will not disappear while effects on halves of Bitcoin block subsidy can be easily seen from Bitcoin's
controlled supply and next Epoch.
The most important thing to do for them is to take advantage of the current situation, we are in the bear market, so the order of the day is just accumulate.
Experienced investors will feel more ready to do accumulation during bear market and they even prepared their capital in a bull market for accumulation during bear market. With more experience than newbies from previous market cycles, their better capital and psychological preparations are not strange.
More important, with more experience, they will possibly have better risk management than newbies and bear market will less likely be able to affect experienced and careful investors.
Rather than DCA with higher prices along a way of bull market, they can DCA with lower prices during a bear market before bottom is reached and market starts to recover from bottom.
