What they say is well-founded, based on previous cycles, Ethereum's profitability is clearly superior more than Bitcoin. If you are only interested in increasing the amount of Bitcoin, you can trade the ETH/BTC pair. When the price of Bitcoin increases to a certain level, it will almost create a bottom in the ETH/BTC pair, then you can use your Bitcoin to buy Ethereum and take profits out to Bitcoin when the ETH/BTC pair shows signs of peaking. This way you can optimize the amount of Bitcoin during a growth cycle.

As for Ethereum's potential, we don't need to discuss much anymore. If it didn't have potential, big funds wouldn't be racing to issue the ETH ETF and soon there may be results about whether it will be approved or not. In my opinion, sooner or later the ETH ETF will be approved and this will be the trigger for ETH to truly outperform Bitcoin in a growth cycle.
