Bitcoin has broken through its historical high and reached the position of $110,000, while altcoins have been lingering at low levels. So, in the future, will the cryptocurrency market welcome another bull market for altcoins? We need to clearly assess the current stage of the market. Bitcoin is indeed in a bull market, but does a Bitcoin bull market necessarily mean there will be a bull market for altcoins? Secondly, since this bull market is a slow bull, the reversal of the trend, as well as a significant rise across many coins, is unlikely to happen. Since the situation of many coins rising will not occur, will the strategy of waiting for the altcoin bull market be reliable? If the altcoins in hand do not explode, Bitcoin may already begin to consolidate at a high level. Once the Bitcoin trend reverses from a bull market to a bear market, won't altcoins face severe losses? Finally, altcoins will definitely explode, but it is highly unlikely that there will be a rise across many coins; that is a low-probability event. Instead, larger sectors will rotate, and sector rotation is extremely unfriendly to retail investors. This is the main reason why retail investors tend to lose money or lose big during the latter part of a bull market when prices surge. Sector rotation requires a very high level of expertise in fundamental analysis, news analysis, policy analysis, and capital analysis, all of which must ultimately translate into technical analysis to determine tops and bottoms. There also needs to be effective trading strategies in place for protection, ensuring that even if one does not make a profit, they can preserve their principal through a risk control system. Do you really possess all these abilities?
