I don't think investing because of Halving will be wise decision. We have to focus on the price find the dip for investing not only the occasions.
Bitcoin is valuable and will remain to be. Halving is not exactly the main cause of its increase in price and it does not mean that since halving is done that bitcoin will not increase anymore.
I think investing in bitcoin in stable periods of time is very wise. You are accumulating more and more and soon you will see huge returns.
The way the world is progressing today, people are eager to invest in areas of investment that reduce the labor rate and make more profit with less work in a shorter period of time. From this point of view Bitcoin is considered as a smart sophisticated and profitable investment field. People's attraction to Bitcoin will never wane. So we are interested in investing in Bitcoin for more profit with less effort.
