Invest invest invest! Then off investments I would probally buy a Tesla and a Porsche panamera. That would be nice

Buy a load of motorbikes.
Loads.
And a few nice cars (Japanese)

Give some to Cancer research.
Fix up our house abit (it's already paid for)

If I WON $3 million I would first of all give about a quarter of it to a trusted Charity and then with the rest of the money I would buy a couple of Lamborghini's, Ferrari's, Porsche's and a Maserati.
Once I have all of them cars I would put them onto my Dads name and give them out for hiring, and make money from there.
Dont need a house because ive got a big house already.

Well I'd pay off all my families mortgages, pay for private education for my brother and go on a spending streak

Autocorrect wrote The smartest thing to do is invest like 1.5 million into the stock market and then over the years you either lose money or gain money. Then I would spend the rest on friends and my family and give like 500,000 to a charity.

its not smart at all to put all 1.5m in the stock market. You need to diversify your investments. I assume you don't have trading/economics experience either, you will most likely get destroyed trying to trade that kind of volume.

I would some things I want but mainly would save most of it.

buy a house, a rolls royce silver shadow (they're only like 20k) and a c63 amg (80k)...
watches, clothes, furniture for house good technology and the rest to live lol

I would probably keep half of what i win and then with the rest buy a helicopter (maybe) and go to America and drop money out of the window for the homeless people; the only reason America is because i see a lot of homeless people videos on youtube and they are all based in america. So yeah just give it too people in poorer countries and people with no food/homes

A few million would go for a nice car, and a nice house. All the necessities. Then the rest would go to savings and furnishing my house and getting everything I need. Then save.

I'd probably sh*t myself in excitement, clean up, then spend quite a bit of the money.
