Truth be told, I doubt that it will reach 100k, with how the gas prices of the Ethereum affecting the entire market right now, its very unlikely to increase. If they can do something about this issue, most probably the prices will increase but its impossible for this platform to reach 100k.
100k is really a dream for right now, if we want to see ETH at this price, BTC should be maybe 500k. That is why ETH price depends on BTC movement. When BTC starts getting up, top altcoins are getting up either. On the other hand, everything is possible in the crypto world, however for getting this price ETH needs a bit more time as expected. It will take a long time to see ETH at 100k. This chance is 1%, as you mentioned it is definitely impossible. ETH can reach more than 2k, maybe 5k, however, it will also happen in the future. There will not be any difference in ETH price nowadays.
