Then invest it on ICO so you can get some profits out of it. I would recommend buying in Pre-sale so you can get discounts for additional coins. Then hold it for 2-3 months after they got listed then you're 10 Ethereum can get up to 20 Ethereum though it's not as easy as it looks 
. You would try researching first before doing anything.
It is good strategy to earn 50eth at year end having 10eth at the beginning. I prefer investing in new ico projects but choose the best ico that will grant high profit at the end. In one year year you can invest 3 to 4times. Then your 10eth may become 50eth or more if you have a luck.. You would try researching first before doing anything.
