A good idea might to be purchase 1000 DASH ($1 million ish about 90 Bitcoin) You get proof of Stake and will get 2 DASH per week as interest, you so just easily sell of the interest received roughly $6000 a month
This would be a good investment with your huge holdings of bitcoin
Damn, that would be pretty good idea but considering he has $100 million $6000 a month would be nothing for him, with so much money he can start so many businesses that will earn much more.
