No, people don't necessarily "insta dump" dapp tokens because they don't believe in the ecosystem. In many cases, people are simply trading them as part of their overall investment strategy or because they believe the tokens may appreciate in value over time. With the rise of decentralized finance (DeFi) and the increasing popularity of dapps, many investors are looking to take advantage of the potential gains that can be made by investing in these tokens. However, it is important to remember that investing in any type of token carries risk, and it is important to do your own research and understand the associated risks before investing. Ultimately, it is up to the individual investor to decide whether or not they believe in the underlying ecosystem and whether or not they are comfortable investing in the associated tokens.
