I am no tax expert, but I don't think you should under-estimate the length your government will do to get what they want especially your "hard-earned" money.  And it is naive to think that they will play by the rule.  Officially it is $10k, but it can be much less if you have multiple smaller activity/transactions (even in different banks) that add up to a large sum of money.

I am very interested in hearing how you have been or intended to laundering your bitcoin profits?  Even if you sell it locally for cash, how do you deposit that money into your banks without looking suspicious as to the origin of your money?  Are you using it to buy a car or house?  How do you explain to the IRS when you bought a $1 million house and/or $100,000 Tesla  all in cash when you are only making $50,000/yr?  I guess you must be running an Italian restaurant that has no paying customer as a front to launder your bitcoin money..  Or have rolls of hundreds under your mattress
