Hi Guy's,
Where would you invest 10 eth in when you can and why?

10 ETH isn't so much, so I'd just hold it. If you want to spread the investment just pick up some airdrops and join Facebook and Twitter campaigns and a sig campaign, and then keep or convert those coins.
More than $2,000 but you think it not much, wow you are rich man

.
In my country, this amount of money = salary of 10 months, not easy to have a big money like that.
If you really want to keep safe your money, you should keep your ETH, do not spend it to invest into other altcoins and wait the price of Ethereum increases.
