I doubt you really have 2M, someone with this amount of money know how to invest his trasure, but if we presume that you are not lying, the best investment would be to buy bitcoin itself, it's the most secure and reliable currency, you can try altcoin, but recently there is only pascalcoin which is pumped with huge volume, i'm not sure if it can reach 0.001, but you can do this, put half on bitcoin and the other diversify it in many altcoin, some of them will be pumped at some point
I see your point sir, its a bit fishy for someone to have this big amount of money and just dont know where to put it. And yes, buying bitcoin would be the best action for now, bitcoin just keeps on increasing and its really fast. I can say that investing your money in bitcoin would definitely give you a good big amount of profit even just after a year, then do join or invest in ICO's or other bitcoin related projects, just make sure that you will find a project with a good team, then your investment will make profit.
