I also have both ethereum and cardano in my wallet. I also plan to hold on to the funds until early next year, waiting for the bullish season. I have a target of selling my ethereum at $7K and cardano at $2.5.
I also think that the peak of this cycle will come in early next year, but I'm curious about why you expect ETH to reach a new ATH in this bullrun but are bearish on the future of ADA. In the bullrun 2021, ADA hit an ATH of $3.1, is there any reason why ADA could not hit a new ATH above $3.1 in this bullrun? For me, Cardano is developing strongly in both technology and ecosystem, ADA will be better supported and can easily reach a new ATH in the $5-6 zone, even though ADA's recovery in recent times has not been as impressive as ETH's.
Selling at $2.50 is probably just a conservative approach. Development in tech and the growing ecosystem is a good indication but there is not a lot of hype around Cardano at the moment. That is one major reason why some people I've talked to view ADA as a slow horse and might not be the best choice if you want to maximize profits until early next year.
Anyway, it's still a profit if you sell at that price.
That's the problem with Cardano, and that's why it doesn't fit for me.
ADA is good for long term holders, and when I mean long-term holders, I mean a minimum of 5 years.
I might be in the mid 20's still, and investing in ADA is still worth it, but I don't like holding a coin aside from Bitcoin for more than 3 years or even 5 years. Upgrades are very slow until it will come to a point where the token will become unpopular. Yes, the project is developing, but the development takes a lot of time though the good thing is that, whenever they release an upgrade, there are no bugs or glitches whatsoever (at least that's what I saw). Anyway, buying ADA during the bear market and sell it during the bull market will give you yield (as other top coins will).
