One million steem is a lot of steem. With one million steem i will power up half of the steem to make myself a whale so that i can be able to support others here and also myself. Also, the remaining half will be withdrawn and invested in one of my physical business projects so that i can have a back up should anything happen to steemit. It will be too risky for one to put all his/her egg in one basket. So i will diversify to make sure that i am on the safe side. There are other smaller things that i would do, but these are the major ones. Once both investment have yielded much profit i can buy a house and other things from them
