Bitcoin is anonymous, only that it is getting compromised because the IRS and everything that is compromised with the legality of the taxes, are always trying to hunt some money.
Bitcoin is anonymous only for the books but the reality is different. Everything can be tracked through the blockchain public ledger. So we can't call bitcoin truly anonymous.
How would you feel if you are a bank, or something, and you see that thousands of people are making profit with a "digital coin" What would you try to do?
The banks are expected to make negative comments on bitcoin and its usage and that's exactly what they are doing. Some banks are even blocking the account for transacting with a known bitcoin exchange or a dealer. It's a threat to their business because billions of dollars are filtered out of banking channel already and more to go out in future.
Bitcoin has been created to be anonymous, they are only following the tracks of those who are making a HUGE amount of money, not the ones who are just making $100 or $200 a month (because it is nothing)
Why do you think that they were trying to follow those who were holding more than $20k on 2015 in coinbase? Because that money has made more than x12 since then, and it is more than $440,000 at the moment.
That's true! IRS will not employ much manpower to chase the peanuts. They want big players who can generate a sizable amount of tax. $100-$200 earning doesn't make much sense for them to chase.
