Hmm, ok interesting. The 5million seems like a lot of invest in initially as there is no guarantee that you guys will not steal out money. Please do not take this as offence, it's just that there are a lot of scammers out there coming out with unique ways to take people's money, but I would probably put 1 mil in on a little gamble as it doesn't cost much and I bought a load when they were about 10 lsats.
That is understood. Generally speaking, where there is high risk there is high reward.
You don't need to invest anything. (In fact, you should probably not buy altcoins at all. Government bonds are much more safe investment.)
