Nowadays, BTC and ETH both have a 5-year return rate of 0%! Having been in the cryptocurrency industry for so many years, my experience tells me: 1. The cryptocurrency industry is too cruel, eating people without spitting out bones, never bring active relatives and friends to speculate on currency 2. The cryptocurrency industry is far inferior to the stock market, not even to A-shares 3. Newcomers should try not to enter the cryptocurrency circle as much as possible 4. If you must enter the cryptocurrency circle, remember to only buy Bitcoin 5. As long as other coins rise sharply, they will immediately be exchanged for Bitcoin (you must remember this, otherwise you will regret it, trust me)
