I'm not sure what the value is now, but I would bet it is a fraction of a fraction of a percentage of the BTC market cap.
And I don't see how it is going to get worse. Once miners stop passing dust on for free, clients will have less incentive to try to use dust so there will be less dust accumulation.
http://bitcoin.lift-institute.com/killing-the-dust/you just made my point with that link
its is a problem that is embedded in bit coin
Sorry, but I understand neither your logic nor arguments. Nor do I see anywhere in that link that makes your point. Here is the summary at the end:
Bitcoins were created as a money alternative, and no person in their right mind would demand to pay/receive half of a cent, or even less. If the value of bitcoin was to rise 10 fold, the dust threshold would certainly be lowered again to match the real value of bitcoins. We should welcome this change to the protocol as it will stabilize and secure the growth of the bitcoin network while it becomes more and more relevant in the real economy.
Which is quite the opposite conclusion that you have (that somehow the new dust prevention threshold will cause the end of bitcoin). Again, I'm open to debating a coherent argument but I just don't understand what your argument is. Walk me through step-by-step (pretend I'm a bit slow, because maybe I am) exactly how this is going to doom BTC.
they acknowledge there is a problem with dust ... fractional transfers
their answer is a ban on small transfers - essentially a boycott - which really does not eliminate the problem
and under lining the problem is that every wallet contains the record of every transaction ever made
there is no expire date no way to ferret out old data and keep things current
volumes and volumes of worthless information
