In my opinion, as a preparation for the halving and bullrun in the future, I prefer the ETH/BTC pair. Like once rowing 2 islands crossed. When we get profits in the form of BTC from trading ETH, we will also get profits from the increase in Bitcoin prices. This is a kind of doubling of profits in my opinion, if our focus is on pursuing the value of Bitcoin. However, this depends on the trader's perception and amount of capital or the investment itself. If the capital is large and what you are looking for is USDT profit, ETH/USDT is not a problem, but because I am oriented towards long-term BTC investment, I will choose ETH/BTC, I can sell BTC and save the rest if I need USDT.
