Hello.
To begin with,some facts.
- By the 13th of December 2017, the network hashrate of ETH was 130.000Gh/s. Today (this has been repeated most times) we are at 245.000Gh/s. so in just 4-5 months the current Hashrate of ETH has almost doubled.
- I'm really begining to see a pattern on this. Usually, if the market goes down, more GPU's are pointed towards ETH (a safe value, at least for now). It happens aswell the other way round.
- today, the current profit of a 314mh/s rig is just about 300$ per month (electricity cost considered). In Spain, were i live, is just about 250.
- PoS is bound to happen sometime this year. We are getting very close to 100 million coins Vitalik said to be the max number. So at anytime ETH mining can be crashed.
The point is: Is there a coin , considering the current values of the Altcoin market, that can see increased it's price so that mining that coin can be profitable?=? i mean, once PoS is applied, where are you going to place your gpus?? Is there a coin , actually, that can absorb that huge amount of hashrate without making the coin totally unprofitable?? We all know that if a coin increases in hashrate but not in price, it's not a viable option to mine it (unless you bet money on it and you succeed, but i guess noone wants to bet nothing right now).
Let's place ourselves in the day after ETH cannot be mined so it's in PoS version (btw, that day is not very far). Is there a future for those gpus?? Nvidia cards do decent on ETH and very good on other algos. AMD cards do very well with ETH and not very good on other algos.
Is the end of ETH going to kill mining?? Will that enormous amount of Gpus searching for profit , actually gonna destroy any profit on any coin??? What do you think??
The only thing I am concerned about is all the noobs leaving ETH when it goes POS. If they sell their GPUs it will be heaven, but if they do the actuall research then it could be problems with flooding the networks.
I am all AMD and I have around same hashrate that you talk about (314 mh/s on ethash). I can assure you I am getting around 700$ per month (electricity cost deducted already). Ethash is not the only profitable algo for AMD. There is also CN variants and some other more hidden gems (the one that get you that money). Do your research and it pays out.
Disclaimer: The alleged earning is of course calculated at this time. There is no guarantee that it will actually be like that in one months timeframe.
