both are required.
Yep. In case your investment doesn't work out as planned, you will have your savings to fall back on. Never go all in.
But if you ask me, I would say that having savings is more important, given the fact that having savings you can handle your expenses and even invest.
Savings are a very important aspect, but not the main aspect. Especially when you consider that fiat is only losing its value. The longer you hold it, the more value it will lose. That's why investing your money is a very essential part where you can avoid seeing the wealth that you worked your entire life for, is slowly vanishing into hot air. The ratio should be 50% savings, and 50% investments. At least, that's a rule I am working with.
much better to atleast put some inside investment like trading or lending its also a good ways to grow your savings just needs to get some knowledge about whatever investment you are going to enter.
Trading is at all times the best option because everything that happens, happens because you do it. You are responsible for every action. That's not the case when you invest your coins elsewhere. You then depend on what the other party is doing with your coins.
Lending however is not really an interesting market. Especially when you consider how crowded it is. It's a good thing for people looking for loans as the interest rates are fairly low, but if you calculate the time-effort-risk ratio, then it's by far not worth it.
