No I won't. I prefer Bitcoin when I see calculations like this.
ETH can reach new highs but it's not guaranteed at all.
Yes, that means lesser at buying it or not at all. Most Ethereum holders now will prefer to just HODL than to pile more without any assurance that it can go at a new ATH. I prefer that way too and would rather buy Bitcoin for now. It's in a good low where a buying spree can happen anytime that would increase the demand.
As for altcoin choices, I am just looking at other gems but I cannot see one yet that is worth buying. Perhaps when this stagnant market ends we will some new breakthroughs.
