Ether market capitalization

The price per Ether indicates to us how much people believe in the technology. There's a saying that goes put your money where your mouth is that fits this statistic perfectly. The more money people invest in the technology, the more they believe in it, which indicates expansion. Funds raised in ICOs, TGEs, and STOs are also great sources of Ether price increases, since many projects are using the technology successfully. People are putting money in useful projects based on Ethereum.

In the following diagram, you can see how the price of Ethereum has been moving over time with several sudden spikes caused by people's interest in the technology:

Ethereum was born four years ago in 2015, where one ETH was worth $0.31 USD. After two years it was worth more than $1,000 dollars by the end of December 2017. Recently, the price is falling and it's about $142 as of January 1st, 2019. This indicates to us that people are running away from it because they got scammed, because they don't have a use for it, or simply because the hype ran out. The real reasons are uncertain, but what's for sure is that the price is in decline because the technology needs to provide innovative solutions to real-world problems that could only be solved with the blockchain.
