Does one really need to kill himself or herself over investment? Well, to me I will say no because targeting your investment to a well know asset such as gold or real estate to have peace of mind if you think Bitcoin is extremely volatile. Besides there are people who makes investment on a target of short time like when there profits is reached they sell off there investment to have their profits this could be in bitcoin or in real estate.
With the rate of increase in natural disasters and conflict, even real estate investments are no longer safe havens. There was a conflict in my location and people were forced to sell their houses at a giveaway rate to flee violence. However, real estate and gold have lesser risk than Bitcoin.
In every form of investment, no matter how safe it appears, it's important to always play your own safety too, knowing fully well that nothing is entirely certain, so the 50% savings is not actually bad since we can run back to that whenever the person needs cash, but for me, I won't save up to 50% of my funds instead I will rather invest in something I can make a profit on a regular business while I diversify the rest of the funds to other things, not just digital.
Diversification is important because it spreads the risks on investments. Some people prefer diversification of their crypto holding by buying Bitcoin and altcoins. But for me, I prefer to invest in Bitcoin and other ventures outside the crypto market. This is because Bitcoin practically influences the price of altcoins.
