This is no accident. Apparently on Google very strongly pressed the American authorities. Therefore, Google began at a very fast pace to delete all videos that relate to cryptocurrencies and also deleted ERC20 and MetaMask wallets from its trading platform. If the video began to slowly restore may in the near future we will see how the trading platform restore software for android.
But no ETA about when all of the videos will be fully restored. Remember it's so easy to delete them all but im not sure if google will be fully restored the deleted videos. Im even not seeing any correlation with the trading platform to restore the software for android and where are you getting that logic? Im feeling curious caused by how is it possible?
That's right, those video deleted were those who has been reported many times by many people that's violating the rules of the videos such as spam, promoting frauds and many more. But as per the youtube management team, those video deleted can still do appeal if they think that they are not violating the rules for them to re-review again by their team.
