Assume that I bought 1 BTC and price is 8185 USD. I would like to buy ETH with all BTC. Price for ETH is 685 USD for now. In case, BTC is down to 7500 USD. I think that ETH price will be down also. On that situation, how do you think that buying ETH with BTC is more profitable than buying ETH with USDT. There is the transsction fee of 1% in binance. I am confused for that and I do not know how to calculate for break event point. Thank you all friends.
