Thinking of going all on on Eth rather than BTC/Eth split

So I'm really considering the buying opportunity for eth to be irresistible at this time and the returns seem to be possibly higher when the bull starts than BTC would be. But am I being irresponsible by doing so? I've went deep into alt coins and got burnt pretty bad and I also haven't been tracking crypto as closely the last few months but I want to get back into it more. I'm really thinking of putting a good portion a month in ETH 100% but I'm worried about feed and stuff.

When I do go to sell BTC it's usually decently cheap, I can easily find an exchange to sell it on without having to worry about transfer fees and such or gas which always destroys me so that's why I worry about going all in on eth alone. I was considering a BTC heavier split but now I just don't know what to do because I really have always been more into the eth ecosystem but fees always seem to be high when the bull run peak hits and also it'll be harder to sell.

I am thinking a year out here probably to sell so any advice would be grateful. This sub helps me think in different points of view so I highly respect all opinions and just want to pick some other intelligent brains to see how the majority feels at this time. As we know crypto can change fast and I am wondering what the mentality is right now as I haven't been keeping up with the news and crypto has been kind of quiet lately.
