$ETH For U.S. stocks, I wouldn’t dare say where the bottom is, since I’ve been involved for less than a year. But if Ether drops below 2,000–2,150, that’s an opportunity to buy in batches and hold for the long term. Bitcoin at 75,000–72,000 is also a very good buying opportunity. Long-term and value investors can watch this price for dollar-cost averaging. If you’re buying major cryptocurrencies on the spot market, what’s your cost basis?
