POS is fake. dont be fooled. its a bigger scam than bitconnect. a POS model is almost as centralized as ripple, with the power among the cartels that own the most, like bitcoin. its the worst of both worlds.

It is possible for some coins form top 20 that gpu  mining can die in 2018 because of the high diffs. on the other hand everyday there are some new coins born which could do very good.
It is possible to mine them, also new gen of gpu can bring some additional performance for mining rigs..

Of course, because every alt is based off BTC price. If BTC goes to $0 so does every single coin. Until the system changes that is how it will be.

Consider BTC will be 50k by the end of the year, what you're mining will much more.

I will take advantage of the possible wave of used cards that may be coming in a couple months. It will all depend on how BTC does over the next month.

I trade. So mining is a great way to get money into the system anonymously, and with extra fees. So any earnings from mining will be multiplied.

Lastly, it depends how you mine. I'm giving out too much game here, but for example I will not being mining ZEC when the difficulty is over 10 when nicehash is paying x amount. I have 6 equihash coins in my script with over 100 conditions. Constantly tweaking it. Also something fun to do.

I just think a lot of people are pissed they have no gear and right now buying cards is not realistic. At least starting from scratch is not. But for us that have been doing it, we are not stopping. I am still looking for cards. Being pretty stingy at least until I can get a grasp on what is going to happen in the next 30 days. If BTC stays around 12 or under with several more crashes many will get out. But if it hits 15 (unlikely) people will keep mining and more will get into it. And as someone above mentioned, profit is profit. You can think of it is as I am finding a $20 bill on the ground once a day. Or I wake up with a $20 bill next to me. Though I do consider it more as BTC will rise. Nothing is dying.  

The other thing too and the reason I never got into ASIC is because they only have 1 use. Old ASIC are completely worthless. But even a video card that is worthless for mining today, has *some* value for others. Same goes for ram, PSU, boards, etc.

ETH can't even handle cryptokitties. I also used to think that it was going to surpass bitcoin's market cap but right now I am not sure anymore. I think its an overpriced coin and something better (Cardano?) can replace it at anytime. ETH devs don't even comment on the upcoming PoS fork. You know why? They are afraid. ETH owes most of its popularity to GPU miners. When ETH loses its most hardcore shills (which are GPU miners btw) it'll lose its popularity lightning fast.

On the other hand Bitcoin has Lightning Network which is going to pump bitcoin even further this year or the next. When a fool proof app comes out, it will be glourious. (0 fee, 0 second payments)

While Peter Thiel is going long on bitcoin, I think it is stupid to say that it will lose its popularity.

If you have any faith in bitcoin, it makes absolutely no sense to think ETH isn't part of the package. If you are willing to compare ETH to Cardano, feel free to compare BTC to pretty much any coin that has no function. The comparisons don't work that way. The crypto sphere needs both coins to continue to grow, and they will in time.

eth is always the last altcoin to rise and when it does it rises a lot, has always been that and that is part of a huge manipulation, now eth is 0.06 x btc, in few days it could be 0.12, it will rise a lot given time, eth's real price right now x btc is 0.195.

The only think I can tell you is that I see the big picture and I think eth is right now the most complete coin to exist and that is where most of my money is in and where most of my money will be going to.

ETH changed a lot and because of those changes I believe on it. I used to be anti-eth till some changes were placed to the network. The most important thing is the network for me and bitcoin is lagging badly on that, bitcoin has a great name and that is it.

It looks like GPU mining death has already started. A mining rig with 6 x GPU RX 5XX series with modded bios is only making 0.0008 BTC daily while in December they were making 0.0016 BTC daily. I hope I am wrong but things are not looking good for GPU mining.

Thanks Metroid, at the moment I have something like 50% BTC --- 30%ETH ---20% Another Coins

Hey @BitcoinSupremo, you forgot that in December we have double marketcap than today

If you think that, you have no clue.

Coins are measured against sats. End of story. The system has to change.

If BTC goes to $0, so does it all. I can point out plenty of coins that are technically worth more USD today, but selling for less sats than they were sunday. How did they raise in price? It is because EVERY coin is valued against BTC. Doesn't mean you shouldn't buy alts, but it does mean you have to learn how the system works. Check the bull run on Sunday. Then check the eth correction. You really think people bought that much btc and eth at the exact same time? No. Its because ETH is measured against sats. ETH actually hasn't gone up at all sunday. Just selling for just a few sats more is all. EDIT - ETH HAS GONE DOWN SINCE SUNDAY. It is currently trading at -3.5% against BTC over a 24 hour period.

Look at the 1day, you will see ETH is falling. Ignore USD its not relevant, look at the BTC patt. ETH has become a weak coin lately. It fell sub 500 this crash. It is a dump and pump coin. I know 2 groups that have buy signals on ETH, yet nobody is buying. The only, and I mean only reason ETH hit $1400 is because it was pumped by several groups after BTC topped out end of 2017. You will not see ETH close $1000 for sometime. BTC would have to be in the 15k range for that to happen.  

This may change some day, where coins are measured against USD not BTC, but for now any coin is based off how much BTC is worth. ETH could become worth more than BTC (not in this lifetime, I promise), but it would still be worth based on what BTC is worth.

Its kinda like, if the american dollar died, how much would your stocks be? Same here, if BTC died how much would your alts be? You can think of BTC as the equivalent of the USD when trading into alts. That is what you are trading against.

For some reason so many people do not understand that concept. Even "cryptoman" on twitter bought alts for 5 BTC and sold them for 3.1 BTC. And then asked if he gain or lost. Well...um you paid 5 BTC and got back 3.1...you lost pretty bad..
