That's a good question. Due to the design of bitcoin, it is a bit difficult to "loan" them (remember that banking is effectively a loan where the bank pays you interest).
Bitcoins are not fiat, and therefore, can not be continuously printed. Because of this, no one can guarantee to indefinitely keep paying out interest on loaned coins. A horribly exaggerated example, just to make a point, is that if I somehow had 20,000,000 bitcoins in a bank, they could never pay me more than 1,000,000 total in interest just because of the limited supply.
Now, that's more on the theoretical side of things. In practice, a major problem with loans in Bitcoin are the volatile price. If the price rises suddenly, it could become more difficult to pay back interest; or alternatively if the price takes a heavy drop, the investor may lose money as what he is paid is less valuable now than it was at initial investment.
Saving bitcoin is very nice because you can use it in future. If you save bitcoin you can use it to sustain all your need and it may help your family. I think in the future you can also save bitcoin in bank and you can get loan in bank of bitcoin. Bitcoins are not fiat, and therefore, can not be continuously printed.
