I am a bounty hunter, It's confirmed that I've participated in many bounty campaigns several times in passing. Those campaigns I was invest there in the early stages of the ICO. So many Time I loss in a scam project and many time I get a huge profit.
If I have $10000 I will buy several coins like half of bitcoin, Ethereum, and Litecoin. These are the best coins in the market and in the future, I am sure they will give me huge money. And With some money, I will fill the hobbies of my mind.
Ethereum does not have a competitor at the moment. I think NEO is the best competitor for Ethereum in the future. The only real competitor of ETh is Neo, this is already an operational platform. But No one knows which one will take his development to another level.
