I estimated he was 36% done. So maybe another 4 months of dumping.
He's currently working on block 6539.
If you list all the initial distribution CLAMs in reverse order of the block in which they were created, block 6539 is 27% of the way through.
I don't know of a better way to estimate how far through he is.
Somehow I cannot believe a person who s one of the major crypto currency holders with so many addresses to dig simply to be unaware of how much money he s been losing by this mindless dumping. There must be a plan behind this, maybe needs lots of BTC for something soon.
