There are also entirely anonymous cryptocurrencies with no readable public ledgers. Everything is still decentralised, no centralised control of any kind, but you can't see what people are doing (Monero and Zcash being good examples. Signal uses Mobilecoin, which still needs to stand the test of time).
There is still a long road to go before there is a fool proof anonymous, liquid, consumer friendly, usable cryptocurrency, but it is the last bastion of defense against complete total state and corporate surveillance. - One of the greatest threats to human life, on par with climate change.
Your use of the word "craptocurrency" is rather childish and naive. Eventually you will take a closer look at the situation and reconsider. Good luck
