Halving doesn't really have a connection to that. It's already common to see that investors want to diversify their investments by putting as much money into considered good and worthy investments and if some of them are crypto-enthusiasts, not just because of halving but they will just continue to accumulate as much bitcoin as they have. Personally to me, I don't have decent money to invest in several diversification which is why the considered options are only limited.
Real estate is not a joke and it requires big money to play with. Maybe the other good options for average investors are stocks or considering opening and starting a real-life business and investment like opening a physical store e.g. food, hardware, shops, general things, etc. or something like a service that is in demand in the community.
For what is the good investment to choose from, refer to the time when the pandemic hits the world and try to research the investment that got boom during that time amid people didn't have enough money to cover and support their daily lives.
