And those kind of projects are the once always having one problem to the other. Upgrading issues, site maintaining issues, and others issues so before you know that they have collapsed in the midst of confusion. Please steer clear and buy and invest in popular well known altcoins projects like Ethereum, Solana, Litecoin, dogecoin, and few more. Avoid any coin that is not improving in value.
The Upgrading issue is largely responsible for the failure of most altcoins as investors lose interest when they enter the application or associated site specifically for their coin selection and do not find an attractive combination of elements. Similarly the issue of security of the site is definitely important because the security of the invested capital is mainly on the developer team. Therefore, other factors recommending increasing investment attractiveness remain with the top altcoins and investors invest with confidence. All the projects you mentioned are top notch and their market cap is relatively good. I prefer to choose Ethereum.
