The 5-year return rate for ETH is 0. If you're investing in crypto, only buy BTC. If you still have ETH now, swapping all your ETH for Bitcoin is still a wise choice! After so many years in the crypto space, my experience tells me: 1. The crypto world is brutal, it devours people without mercy—never actively bring relatives or friends into crypto trading. 2. The crypto market is far worse than the stock market, not even as good as A-shares. 3. Newbies should avoid entering the crypto space as much as possible. 4. If you must enter the crypto space, remember to only buy Bitcoin.
