Know what happens if it's your coin that happens to decay? Your computer explodes and you die. You fucking die.
I don't think this is a practical idea, it would require expensive and dangerous custom hardware. How about it just deletes some of your data instead?
Other than the part about fucking dying this is a great idea. You should release it soon. I'll put a 5830 on it right away.
Haha sure. Amendments are welcome. Data loss could be nice. But, the incentive must be strong enough for people to convince others to join, no matter what the cost. If the whole world adopts it, nobody has to worry about the half-life. But if you're one of only 10 people with a Radioactive Coin, and your life is on the line, I bet you'd go to some pretty crazy lengths to promote it
