Ohhh 10 million Steem, the options are endless but I know exactly what I'd do.
Firstly, I'd find every account that comment spams and plagiarises and give them $100 USD worth of Steem each before flagging their account to invisibilty. That way, they wouldn't be able to clog up the community with their crap but they would have some Steem to withdraw as cash to help them start again, hopefully in a more productive and beneficial way to the community.
Then I'd hit some of the circle jerking self upvoting whales whose posts never get read but who make a fortune everyday simply by their autovoting friends.
I'd then pop over to fundition.io and look for some struggling young devs to help out with a decent delegation to keep them going and aid their work.
Next, look out for some great real world charitable projects that need some funds, especially in the areas of poverty, homelessness and the environment.
Then I'd give huge upvotes to all the people who have bothered to engage with me on here before looking for plankton who work hard but never make anything yet don't give up.
The amount of joy, happiness and life changing gifts you could give with 10million Steem is almost immeasurable and even if you never took any of it for your own personal financial gain, the absloute joy you'd bring on yourself doing so much good would keep your spirits high for the rest of your life.
okay im upvoting you now in case that becomes true.. hahahahaha
hahaha you are a tart my friend, but I will return the favour for your blantent cheek lol ;-)
