That does not make any investment and all those things you have mentioned are just the benefits of an investment. We all want profit from an investment but we also have to consider all the risks involved. If we are capitalizing on the risk of any investment as not being safe, then one is absolutely not ready to invest in such situation.
As long as it is an investment, there must be a risk attached, it now depends on how you want to weigh such risk to the investment you want to make.
