I believe that this was a temporary short-term effect, especially since Ethereum has already regained the second place in the list
It happened before that XRP replace ETH on a number 2 spot but it will not last for months. ETH now still on top but of course if XRP continues to pump like this, then we are entering in a bull market again since many investors are coming in and XRP may take the lead agains ETH.
The same time as last year, the XRP pump price was very high and then at the end of the year the market rebounded, BTC and ETH rose sharply. And the XRP overtakes ETH is only temporary because current ETH has returned to the second place with a market cap of $ 25 million.
