You can use it anonymously or better said, "pseudo-aonymously" or how should i call it?Just buy btc without any trace to your accounts or person, use vpn and maybe not your home internet connection (better to use a prepaid sim) for the transaction! Voila!
Nobody is able to connect this transaction(s) to your real person! It is possible to mix them or to buy monero/ dash and sell them again for btc.
But the best thing is: NOBODY and NOTHING is able to block, delete ,steal or freeze your money. It's all in your responsibility, not the banks or state or someone else, it gives us the power back!
Yeah I would say "pseudo-anonymously" is the right word. I am aware about the concepts of hiding your IP-Address and stuff because I am a computer scientist but tell me how are you able to make a really anonymous transaction from Fiat currency to Bitcoin i.e. as it always includes a transaction from you bank-account. I am really new to this whole crypto stuff, so apologize my lack of knowledge.
