Its better to invest these days because the halving is coming and it has a really good future of you ask me its all just a matter of time.
We just need patient and hold our bitcoins for the future.
Don't make a investment, just buy as much possible with real cash and hold it. So that within few months due to the halving occurrence will get a good profit.
Investing is still good to earn as much as you can before the halving comes,you can invest for 3 months then let it go as by that time halving is really near.
Saving money is very good, so you wont lose money and that is the best thing. Otherwise you will lose it.
And that is not good. You can lose money with making an investment.
Saving money is always been very good of course but if you will invest only some of your money you can even make more money once you will know that how that investment can work for you. This will even encourage you to engage in business to let your money grow..
