Why didn't I buy some of these years ago!

Now worth over $1000 each, years ago their value was about $10, but I thought it seemed like a con, so I didn't buy any.

Anyone bought any?

Anyone think its still worth buying them?


I've had a look at the economics of it and given the fact there is not an infinite amount of them, the price should continue to rise, but its the whole non regulated and generally used by criminal factor that has put me off.
