I have quite a few altcoins and I understand that a few of them may not do well but most of them have been doing great last few weeks and will continue to do so next year.
I don’t hold any Ethereum , never been that keen on it - fees are too high. And I prefer a few other altcoins in the current top 20.
If you use Ethereum to be sent via the L2 network it is not expensive, like using ARB, optimism you can buy ETH and send it without worrying about costs.
ETH so far does not have ATH in this cycle so there is a possibility to print ATH back in this cycle and is still quite far from the current price of ATH.
Choosing Altcoin in the top 20th place is quite good, but you must pay attention to their project whether it has a development or not not to buy a dragon that will die in the market, then besides that the price increase in coins that have been at the top 20 is very difficult to get an increase of more than 10x, in my opinion it is also less interesting in terms of return.
