I think Bitcoins saving is quite risky, because compared to other forms of investment such as gold or dollars, cryptocurrency is more risky because the possibility being hacked is so high, we could be stolen bitcoin or the ability the network system attacked, you lost all bitcoin in the second. In addition,fluctuations in bitcoin price are highly impacted by the market so investment in bitcoin is unsafe solution. 
I think newbies like you should make a thorough research first before putting your insights here in the forums, it only proves that you just want to rank up here and later on join signature campaign for profit purposes. first of all personal wallet can't be hacked and 2nd is the prices of crypto will not always pump up and that is the part of the risk of this investment, just like any other investment it will always have a risk attached to it.
Different people on the "safety" is not the same definition, be sure to study it yourself, do not trust anyone. Bank savings and the risk of inflation depreciation, bitcoin although the risk is relatively large, but the returns are high.
