In here there is a saying "Goods are earned from buying" . It means if you are a merchant and want to profit , you have to buy it cheap. If you buy something expensive , you can barely profit it or wait for a long time.
So, invest or save ? It totally depends on what you invest and your time.
If you want to invest real estate , -I believe- Its not a good time for investing. Since there is an economic crysis upcoming . May be in a few months real estate price will decrease sharply.
If you want to invest Bitcoin , -I believe- these prices are low enough to invest , If you dont need money in a near future , It can be a good investment. However if you need money in very short time , BTC price goes a little bit down and you lose your money. Soi saving your money in a bank is a good solution for short time needs.
To summarize, If you have money and dont need in short period , -not and advice- , You can invest Bitcoin, not real estate. If you have money but need in a short time ,keep your monet in a bank.
Sometimes it is better to invest into the bitcoin right now than save money but that depends about how much money you can have and how much you need to life from as you know
The price of the bitcoin is very important to invest into it so make sure you have lots to invest not just couple of hundred,
