ETH has been moving nicely between the upward blue (resistance) and purple (support) Gann lines, with any quick parabolic breakout from this channel turning out to be a false breakout.
Currently hugging resistance, a break above the trend line would be bearish, likely seeing a retrace to the 0.786 fib ($3500). Rising gas prices, an enormous and convoluted NFT bubble, and faster, better, and cheaper competing chains (along with bridges now adding the option to "peg in" to a native currency on any token transfer will reduce ETH demand.
Gann structure indicates a correction to take place around December 10th, with the purple and red downward Gann lines providing our channel downward as we move into distribution mode.
Note on long term viability of ETH. Eventually blockchains will be an order of magnitude better in every way, don't forget this is part of a very new technological paradigm that is providing improvements literally daily. It's not fast, efficient, or even very safe (it doesn't natively stop integer overflow errors... that's not the system we want global finance on). Manage expectations when consolidation occurs; with such direct competition it's possible we never see prices for ETH so high ever again after this cycle.
Nobody uses AOL anymore in 2021, I expect in the next 5-6 years you'll be the oddball if you are active on Ethereum.
