Under current law, is there any way to force the US government to accept and secure a private key.
they already have a bitcoin client and private key. they moved the silk road funds to it.
but i still wonder what your actually asking..
1. you want government to own bitcoins?
2. you want to make a random donation to them?
i thought they already had enough funds with fiat. why give away bitcoin to them, its rare remember. you might aswell give all your gold and silver jewelry to them for no reason. i would also say your house, but the way mortgages work, they already own your house.
Which is total crappy yet why would forced them to secure a private key?It turns out that you are putting a gun in your own head when you do such thing. Giving out free money which it shouldnt really be done. This is why most people do love crypto because of this matter. Once you hold the keys you are on the full control of your holdings and no other will able to take it from you.
