It depends on where you are located. Saving your money in your bank is an easy option but not very lucrative.
In fact, I have read an article about banks who are going to charge negative interest rate on your savings account. Which is ridiculous of course.
I would choose for spreaded investments. Leave 70% of your money in your bank, and invest 15% in Bitcoin and the other 15% in something like a Bitcoin startup.
For me its better to invest here in bitcoin because bitcoin is trusted in the field of investing but i dont have enough knowledge about it so i am joining signature campaign and the money i got there is going to my wallet and i will going to save it.
