There are 3 Ethereum hard forks lined up for this month of January.
- Classic Vision Hard Fork
- Ethereum Nowa Hard Fork
- Constantinople Ethereum Hard Fork (Major one)
1. Classic Vision Hard Fork
Ethereum Classic Vision will be a new currency created after the Ethereum hard fork and this will leverage the best of Ethereum Classic (ETC), i.e. true decentralization and the Ethereum (ETH), i.e. PoS mining and sharding.
All Ethereum hodlers will get 3 ETCV (Ethereum Classic Vision) coins for every ETH in their private wallets.
This hard fork is about to happen on 11th January 2019 – Ethereum hard fork date.

2. Ethereum Nowa Hard Fork
Just a day after the Classic vision hard fork, on 12th of January, 2019,Ethereum Nowa Fork will happen, where the ETH owners will get 1 ETN (Ethereum Nowa) coin for every ETH in their private wallets.
3. Ethereum Constantinople Hard Fork
This is the major and the most significant ETH hard fork happening between before 14th to 18th January 2019.
The Constantinople Ethereum hard fork, which is the 2nd phase of the Metropolis project, is expected to be built on 7080000 blocks, improving efficiency and performance.
This is undertaken as a step to transit from Proof of Work (PoW) protocol to Proof of Stake (PoS) protocol (Casper update). This is expected to make the ETH network faster and less costly to operate. It might be controversial as it would decrease the miners’ reward from 3 ETH to 2 ETH as well.
The Constantinople hard fork is a part of infrastructure and protocol improvement for Ethereum blockchain, so we don’t expect any new coins from this.

What Must ETH Hodlers do?
After the Classic Vision Hard Fork, the owner gets 3 of ETCN for every ETH they have, after the ETH Nowa (ETN) Hard Fork, the ETH owners get 1 ETN for each ETH.
You will receive the new coins if you have your ETH in a private wallet (Metamask, Ledger Nano S, Trezor, Myetherwallet, Imtoken, Guarda) where you control the private keys.
If you have your ETH in exchange wallets then you will receive new coins if the exchange supports the respective hard forks. You can closely follow all the updates coming from the exchanges.
We also advise not to import your wallet private keys to any new unrecognised wallets promising free coins.
