Ethereum 101Most people really dont understand Ethereum, which is going to be damaging to the market. I have heard friends and have seen posts even on here with people who are investing that dont even understand smart contracts, proof of stake etc
Did you know their are 2 Casper's? When you invest in a coin, how much time do you spend researching it? I normally spend at least 3 hours learning everything I can from it before I attempt to make an investment of even $1. It is important to understand the coin from a general level, and if you can understand it from a technical level that is even better.
Well what negative thing I think Ethereum can do to the market is still based on the users who will going to use the benefits of ethereum. The smart contract is good but when it is used in a less valuable manner, still ethereum will be subjected to the result.
