Let's say something about the Pi network from my own experience!
Part one
Pi Network is a project that aims to make digital currency mining accessible to everyone, through a mobile application. So, it's free to everyone. Unlike some other cryptocurrencies that require a lot of power and electricity consumption for mining, Pi Network allows its users to "mine" on smartphones, with minimal battery consumption.
The Pi network uses a consensus mechanism based on the Stellar Consensus Protocol (SCP) which makes it more energy efficient than systems that use Proof of work (POW).
The plan and aspiration of the community is for Pi Coins to be used in real transactions within their own ecosystem, including e-commerce and DApps.
According to current information, Pi Network has over 60+ million users, which is the largest community, and also has 14+ million KYC verified users, real people not bots.
The most frequently asked questions on the Pi Network forums are related to migrations and the KYC verification process.
As for KYC verification, there are certain problems related to the validation process itself by the validator. Just completing the validation process for some users takes several months, additional checks are often requested, there are problems with cameras and blurry images of documents, incorrectly entered data, and so on.
Also, it's necessary to distinguish new users and old users who were inactive for a certain period and did not complete the KYC process.
Therefore, new users automatically receive an invitation after 30 mined cycles, and if they fill out the prescribed form without error and follow the instructions, their request will be revised very quickly and the KYC process is thus completed. I had several friends with whom I went through the process and there were no problems, so it is possible without problems
Other users, those who have been inactive for a period of time and have not completed KYC, are now having trouble accessing the KYC process. By running KYC in the Pi Browser, a notification appears that there are currently no free slots, and that they will receive an invitation as soon as one is available. This refers to how PINetwork says a small proportion of accounts, identified by the algorithms as a potential violator of the terms of service, will not be eligible to KYC just yet. If account owners think they were identified by mistake, they can submit for further investigation by filling in this form... After filling in the form, an automatic response is received, but the problem is not solved. It is not certain when the KYC verification of this group of users will be resolved.
So much for the first part, if there is interest in this topic, I will think about the continuation.
