If I would get such an amount I would simply just hold it and store it for a long time to make some good money in the future.
I'm pretty sure with such an amount that you can make nice amounts of bitcoins for sure.
Holding all of them is not an good idea, some of them should be used in trading to grow the number of coins over a period of time as if price falls in future then your holding will not give you profits.
For me if i had that amount not all amount i invest in trading just few and i will try other ways to increase the amount of bitcoin like starting my own site and monitizing it and use some bitcoin to buying domain and paying for seo to increase the rank of my website that can be increase more profit in the future if i am success. just like other faucet owners..
