I just created this thread to gather opinions ..
Ethereum is next to BTC?
Bitcoin and Ethereum are actually using a system called Block Chain. In this Block Chain system, data recording and transactions are performed on multiple servers that are connected to each other. That way, if there is one server that is damaged, the data can still be accessed on other servers.
The thing that distinguishes Ethereum from Bitcoin is the application of Smart Contract, which allows you to program transactions, before you do it. For example, you can create an arisan program that will automatically move the Ether belonging to each participant to the winner's account each month.
