It uses proof of stake, meaning it becomes more centralized over time. That's the last thing you want in any good cryptocurrency, but particularly one which is supposed to be focused on privacy and censorship resistance. Proof of stake cryptocurrencies can never be censorship resistant, as the recent hilarity with Ethereum shows, with somewhere around 80% of Ethereum blocks current censoring transactions to comply with OFAC regulations: https://www.mevwatch.info/

So sure, that particular shitcoin might allow you to avoid having to download the entire blockchain, but it is neither private nor censorship resistant. If avoiding downloading the blockchain is your main goal, then using bitcoin with a light wallet such as Electrum will be far superior.
