If I have 15 million dollars (wow! that's a lot!) , I will invest 25% of it on Steemit... 40%, I'm going to use it on various business ventures (realty or restaurant, etc). Another 15% would go to savings (emergency purposes)... And for the remaining 20% I'll use it on myself and my family, relatives, friends, charity works, etc...

Ohh~ life would be very merry with that amount.. lol! ^^
