This chart represents the notable L1 smart chains which are all competing to be the "eth killer" and cement themselves in the top 10 cryptocurrencies.
The date range should start from 21st July 2020 which represented the "market bottom" for Bitcoin and crypto. Each project did of course start in different places in rankings due to their market caps however... The chart can be used to recognise the gains made since the market bottom amongst the smart chains, along with the "ebb & flow" of the money between chains and on the pumps/corrections, helping to time entries/exits.
I think it is also a good example of how "spread betting" or having a diversified portfolio in L1 smart chains within this market can be a really powerful strategy. Not financial advice just a trend which has been noticed as this industy most value is expected to be captured at the "infrastructure" layer and not the "app" layer.
