Guys, nothing to worry about, ETH will grow in 2018, and very good. It's time to buy. The price is very attractive! Besides the Vitali Buterin provided to the public the decision for scaling - Plasma. This solution is an external level of smart contracts and will help improve the network bandwidth of the ether.
So far, all representatives of the ethereum community have to download and confirm each smart contract in the Plasma system. But soon the developers promise to reduce the amount of necessary data.
When the internal transactions are used in the system — "Plasma coins". Tokens are generated when a user submits funds to a contract. So, instead of downloading and verifying all the data, you can simply keep track of the internal coins.
Plasma acts similar to the Lightning Network of bitcoin: transactions are off-chain and are recorded in the blockchain when the channel is closed.
