It's because their claim system is really hard to navigate. I just got my end completed last month, after working on this claim process for what seems to be a year now, and they keep sending me emails telling me to finish, which only confuses me because I am done. It took me until last month because I actually quit trying to claim at one point because the whole system lead me to dead ends many times. The claim process was literally broken. Right now I have it all linked up to kraken and i'm having them send me cash and btc and bch there. It is still unknown how much of each, I don't want the cash, but once again they bundled that option together with the kraken claim process. Supposedly I will get my funds in another 60 days, they said 90 days before, but I am not sure what this extension thing has to do with me. Maybe that means I won't get the btc at the time they said because they are pushing it back. I don't really expect anything at this point, the claim system was so "hokey" that I think it discouraged a lot of claimants and indeed they are sitting on a pile of unclaimed btc at this point.
