if you give me 10 bitcoin, I will use it to invest. Why invest? because if we invest, the money we will continue to grow, I think 10 bitcoin very pretty and nice to use to invest
But where will you prefer to invest? Online investment sites or real life products, as if you are planning to invest them online then you need to be very careful and smart in choosing any investment.
Yes, because online investment is risky because we can't trust on any sites, and we know that mostly sites are fake, even i have an experience of it, that's why i always suggest that online investment is not trustable but not at all. So better is that use the 10 bitcoins in gambling. May be gambling give you double.
