I don't think I know much about ETH, and I don't even know how the ETH's smart contract is used, but I know that it's a bull market and that investing in ETH can make me profitable.
I think we are hundreds of people that just know that Eth is profitable. I want to know more about it but to be honest, it will take many hours for sure to understand it for people like me that has no background on programming or any tech related stuff so I'll wait for my local news to explain it all.
Yes many hours or maybe a day or more to understand the technology.
I am also not basic on programming, so its difficult to really undertsand. But at least now i have profit from it. Thats all i understand.
