The project is being very disappointing. Not only for ICO investors, but also for miners. Initially, it was supposed to be only CPU minable only with Argon2d. Then we found out that GPU mining is more efficient and my hardware got obsolete in an instant. Now, I am surprised that they want to get rid of all Proof of Work and replace it with Proof of Stake.
Very disappointing mining this coin. You don't know what to expect from the project anymore. Even the discussions of vested accounts of mining POS is bad. Just saying...
Have you read the original whitepaper?
https://medium.com/nimiq-network/nimiq-a-peer-to-peer-payment-protocol-native-to-the-web-ffd324bb084Nowhere does it say it's CPU only. They mention Argon2d and ETHash as candidates, both are CPU and GPU minable. Regarding PoS, they wrote:
We would strongly prefer to switch to a Proof-of-Stake Algorithm in the long run to get to a more energy-efficient Blockchain system.
If you are saying it is "supposed to be only CPU minable", then you have a vision different from the Nimiq Team vision as announced in their very early days.
