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
