The level of Bitcoin decentralization that has been achieved is largely based on the fact that there are already many miners that require huge computing power to find the hash. This is what Satoshi Nakamoto predicted in the White Paper. Initially, bitcoin was much more vulnerable.
Therefore, I will not undertake to predict whether some other decentralized project will appear in the near future. After all, even if it has already appeared and is starting to work, in order to reach the level of Bitcoin decentralization, it will need to become quite popular. And at the initial stage, even a promising project can be compromised.
