According to the frequently discussed 4-year cycle theory for Bitcoin $BTC , the potential for a correction towards 2026 and even a "dip" near the $30,000 band following the 2024 halving would not be surprising from a market psychology perspective. In past cycles, sharp pullbacks have been observed after peaks, followed by a long horizontal accumulation process. If this scenario repeats, the period between 2026-2027 could require patience, and the foundations of the real major bull run would be laid during this process; the new peak is expected to align with the cycle logic around the end of 2028–2029.
On the altcoin side, the situation is generally harsher and more selective. Even large projects like $ETH can experience significant value loss during downturns, while many weak projects can be completely wiped out. However, when the market revitalizes, altcoins with strong narratives (like AI, RWA, L2) offer higher return potential than Bitcoin. In short, a possible 2026 dip scenario would be a "cleaning and opportunity" period for altcoins; the quality projects that survive will be among the biggest winners at the 2029 peak.
