I do believe we do must do both, because at crypto world, having some coin might mean we will get a bigger value, with saving, with investment we can grow our bitcoins fast as well risk to loose them.
currently look like that risk is not as mush as the chance of increasing the value of bitcoin in next few months so investment in bitcoin can e proof as a good decision,
You can almost never predict that. In the past the prices have gone up or down in the times when it wasn't expected. However, bitcoin is not a good investment currently, because the prices might not go up to get a good ROI.
