the anonymity of bitcoin is very good indeed.
also the fact that you don't need to sign up anywhere to send/receive it online is so good.
because it is unlike fiat where you have to sign up at paypal for example and they will block you if they like.
Many things that I like with bitcoin and a lot of advantages.
Well for me , that is given about signature campaigns, I like the best for bitcoin is that, every time you are using it for transactions, sending payments for the goods you are going to buy or services. Just wait for a while or a couple of minutes and your transactions are already done.
And that's what I like the best with bitcoin, the transaction is very fast with low fees.
