very simple answers.
1º Most part of the mining community, is ruled by greedy bastards that are pushing ASIC everywhere around, to fu.k up all gpu miners. GPU mining is a market open to people from almost everywhere, and that can builld systems almost right away, and win some money to live. I still remember a guy from Venezuela that used mining to pay a lot of bills, including his mother's operation. This is WHAT MINING WAS ABOUT. To give and share money to all the community so that they could do better in live. Those greedy guys pushing ASICS are actually MORONS, that are destroying this market for the rest.
2º The ETH community said nothing to ETH not going ASIC resistant. Why? Because what ETH wants is to get a big network build as soon as possible, and they don't want that to take long. The faster PoS is applied, the better FOR THEM, NOT THE COMMUNITY. That's why Vitalik is sharing his money with different projects, because he knows for a fact that not making ETH ASIC resistant many people in the third world mining are getting rekt.
3º As time passes by, more and more GPU's are joining the network of ETH. This is because ASICS are taking control of every coin by CENTRALISING THE MINING. If you can take control of a coin, mining to , SO BEING THE ONE TO SUPPLY IT TO THE COMMUNITY, YOU CAN ACTUALLY MANIPULATE THE PRICE. The same has happened all the time with PETROL-GUIDED COUNTRIES. ASICS are destroying the world of mining AT FASTER RATES THEN EVER. But the community says NOTHING, because a big part has already sold their GPU's and bought ASICS. People don't actually care about the others, just want the most profit, and fast, because they know that this is ending. It's like watching coins drop from a machine, and see a lot of people running towards them, and getting a big part. Instead of taking YOUR PART, you´ll try to get , your part, his part, her part, and others part. This is GREED, and for me is a CAPITAL SIN.
4º GPU mining is still giving little profit, but the profit can disappear tomorrow. The value of the coins are in a critical point. For some people, it's just not worth mining though they get little profit. Others are mining because in their minds, they BELIEVE that mining and don't sell is a part of this matter. If ETH increases in price i will get more money, they think. They will get totally rekt because this market is dying.
5º Day after day, ETH network hashrate is increasing. Difficulty has scaled 13% in the last 30 days, which is fuc.ing ridiculous. And still going up, because the more ASIC joins different coins, the more rekt people get mining it. That has consequences: The increase in difficulty AFFECTS ALL THE PEOPLE.
Reality is, ASIC miners rekt GPU miners. Now new ASIC miners are destroying all ASIC miners instead. The harder the difficulty, the less profit. FOR EVERYBODY. An ASIC miner is not BY ANY MEANS LEGITIMATED TO TALK ABOUT ASIC MINERS. Greed gets FEEDBACK from GREED.
Now , what to expect in the future?¿? The big GPU holder is now ETH. Not a single coin can even get to the 1% of this coin (unless ASIC coins , obviously). A big part , like 80-90% of the World's GPU are on the ETH network right now.
Well, ETH will go PoS (this is my guess) around q4 this year. If out there there is a coin profitable, with the end of mining for ETH, there will be no coin left profitable unless a miracle occurs and some coins begin to gain value.
You see? many people , before this big crash, were mining alt coins in a type of investment. They were losing money (electricity bill) but they thought that coin could multiply it's value by a lot. Now people are so fed up with this situation, that they are only mining for direct profit, NOT FOR FUTURE PROFIT. Why?? Because noone believes in this market. NOONE, not even investors. Thats why prices don't go up from low, and after a small push, there is a small drop to compensate.
Till ETH goes PoS we can still gain some money. Hope ETH will not go PoS till at least it reaches 800$. Why? Because i think when PoS is applied, small hodlers, (with 5 or less ETH), will not be able to enter the PoS verification system, and they will be forced to sell their coins. A huge amount of coins will flood the market, time when sharks will stay calm waiting for those coins to lowe their prices for them to buy. Moreover, i don't think ETH can survive with only the money from smartcontracts. It has a value of 468$ right now, because it can be traded, bought and sold. Once PoS is applied, my guess is it will go down by a lot.
Once thing is clear for me. Once ETH goes PoS , there will be no more coins profitable to mine in the hole market and GPU mining will die. ASIC miners will last a big longer. There is NO PLACE TO PUSH SUCH A HUGE HASHRATE OF ETH. No way.
