This week Ethereum has increased 23.90% but is still under $4K. Bitcoin has crossed the $50K price or is already at $51K and is almost heading towards $52K. Data-wise, Ethereum is not keeping up with the effects of Bitcoin's rising price and I'm not sure Ethereum will hit $5K later this month but I'm aiming for $5K by the end of the year.
Could you share more information that support your opinion that "Ethereum is not keeping up with the effects of Bitcoin's rising price", because afaik Ethereum usually follows the rising effect of Bitcoin's rising.
The data can be seen on the coinmarketcap website. Logically what happened this year when the price of Bitcoin had reached $52K, the price of Ethereum was still at $3.7 and $3.8.
Then you can also compare when the highest price of Bitcoin occurred this year was how much Ethereum was at that time. To me that's a rare occurrence in the crypto space.
