1. if ethereum jumps from PoW to PoS then ethereum wont see growth to 1000x.. because PoW has real underlying costs to make blocks but PoS doesnt. so ether wont have underlying acquisition costs holding it up as well and has more potential to go down when PoS block creators get rewards at no cost so will sell down the market..
1. May not be true due to speculation, a boost may come from the investor sector if they see this as essentially a dividend. It also could get those who are worried about the negative press and reaction to large power usage.
speculation is just waves. not sustainable and normally corrects back down to underlying value. though new ATH are great for media, drama, conversations.. the actual price event never lasts long enough for everyone to have enjoyed/took advantage of. whats more important is the sustainable long term prices that everyone can take advantage of.
EG(using bitcoin price stats as example)
2017:>900
2018:>5800
not many took advantage of 2017's $19k+ but EVERYONE even you right now can take advantage of the 6x rise from 900-5800
these >900 >5800 are build up from th underlying bottom value made up of cost of acquisition
anyways sticking to acquisition costs
imagine that gold costs $1k to mine and the price of gold was $1100..
then imagine next week they found a way to mine gold for $0.01
all the gold miners will sell their coin not for a bottom limit of $1k to break even like before... but for any price above $0.01 to break even with the new method.. because anything above a penny is profit.
you will also see those market investors. wont want to buy gold for $1000+ because there is a way they can get some for a penny. so they too will become stakers and grab the rewards and then sell down the market further pushing the price down.
because ofcourse why would they buy at $1k on the market if they can buy some for less elsewhere
that said. my point 1 and ur reply and my reply are all on the scenario of a PoW to PoS flip. and me just saying it will cause a price drop of bottomline support value.
HOWEVER
seems alot of ethereum devs have recently agreed that in a couple months they are thinking of changing the ether block reward from 3eth to 2 eth but didnt mention a change to PoS..
and so under that scenario with less ether per block but still doing GPU/ASIC (PoW) mining. the reward goes down which means while PoW mining remaining. the costs rise due to hashrate rise. but the reward drops so the cost per ether goes up. meaning PoW miners are not going to sell for less then their costs. which. if the rumours of them dropping to 2 ether is true then ethereum will go UP in price. due to acquisition costs rising.
