The stupid thing is I can leave bitcoin in my wallet at home. Cross the border into the United States with zero bitcoin in my phone wallet. Access my home computer remotely once in the US. Send my wallet phone in excess of $10,000 bitcoin.
When I'm crossing the border I can be totally truthful and state I am not carrying more than 10K worth of currency.
From what I was told from your Americans is that you can't do that because your country reads your email so you can't do that if you do then you go to jail. You are no longer free like your granddaddy was. Sorry Americans.
i don`t understand,even your country reads your email,how they know you tranfer your bitcoin after you cross the border?
My progressive/socialist/democrat country doesn't ask me at border yet to declare stuff like America does under penalty 10 years jail and our commies haven't put 5 people in jail for taxes yet your America has millions in jail. I hate that my country hates freedom and regulates everything but they suck at their job so I have more freedom right now then America problem is America is good at it and is forcing my country to take my freedom more and more which is happening slower then in America but we are all loosing freedom that is why I ask you America and uncle sam please go back to your old ways when you use to be a freedom loving country and lave me alone! Let me be free stop your anti-freedom regulations love the old bill of rights your grandfathers use to have! Is that to much to ask?
i think you are a little bit out of topic...the question is: how do they know you tranfer your cryptocurrency out of the country...any country..not just america.
Re-read the topic title.
And maybe stick to the cawing crow routine i heard since 2013.. they can't stop us.
..like the guy who posted that tired old fail cliche earlier here.

News Flash.. they can and they DO !
Meanwhile some guys using Localbitcoins in Florida were arrested by the FBI in a parking lot.
If they try and stop Crypto then yeah it's going to have a massive impact.
Just because some users get away with it occasionally makes no difference.
For example..
How many of you cocky stupid mouthy retards used PAYPAL with crypto ?
Had your account seized yet ?
I don't need political rabble from noobs.
It doesn't matter which party is pulling strings.. they are all same shit different pile.
You all want to spout off like you know things with your noob accounts.
But line up and raise your hand if you paid your taxes on any crypto profits.
yeah i thought so.. so STFU idiots.
Get smart and do your homework morons..
