The second is YOURChain or course.
YOURChain is the third.
1. Bitcoin
2. Rchain (huh)
3. Yourchain
but the question was , The first great project was Bitcoin. What was the second? , EEUHH Rchain never was a great project , it is nothing and Rchain was nothing , nr 1 and nr 2 , i agree
I assumed Ethereum was the second.
It is clearly DogeCoin. the second revolution: anyone could join in, anyone could mine, and anyone could participate!!! (even cats). When I read this thread I get goosebumps like when I was introduced to Dogecoin. I have a feeling that the spirit of the Shiba will channel through the Trump!
