I wrote a long article about Ethereum scaling history. But there is no point in posting it. We all know that ETH has failed. With current ETH and gas price at the moment 1781$ and 239gwei on average single transaction cost is around 9$. With current prices network renders itself as unusable for almost everyone and only very big players can benefit from using it. ETH2.0 is in Phase 0(The beacon chain) but they still have not decided what should happen in each phase so i don't expect it to see before end of this year. Existing 2nd layer solutions with current prices are also useless. Sadly this has very negative effect on whole market and there is no time horizon when this might be fixed.
