The nature of crypto as a small, emerging and high-risk market makes it difficult for any project to sustain its progress and that is for many reasons, one of which is competition between multiple entities targeting the same domain, such as smart contracts. platform, there are dozens of projects in this domain and many of them are either useless or just clones of other projects. Another reason is market cycles forcing unprepared or inexperienced project owners to close, which is why I expect many of the top 20 to be non-existent when the next bull market starts.
