This makes no sense. Correct me if I'm wrong but pretty much any cryptocurrency can be transferred to an online wallet then accessed and used from any where in the world.
Who walks around with their entire crytpo portfolio on a single device? And even if they discover bitcoin for instance on your phone, they can t do anything about it...change it, seize it....nuffin...
Even if they take your equipment, the blockchain makes it easy to simply reestablish it on a new phone etc...
This seems like a silly attempt at control by people who are clueless.
Update: i did a little reading on this and indeed it appears this is bs and totally unenforceable.
What's is there stop the transfer cpryto to someone who has already gone through security. Absolutely nothing...
I also read through some of the bill itself and it appears to me that its the crypto exchanges they are after. Positioning them as facilitators of an illegal transfer of funds across international borders. This makes more sense.
My guess, etherium/big-banking is taking a run at bitcoin via washington.
