Do you think in the past year and a half (since ATH), has there been a quiet redistribution of bitcoins?
Redistribution? Not really. I can't see a major flow of bitcoin from large holders to small users. Early miners who holds thousands of bitcoins aren't really selling. May be a few to buy things and gamble a bit. Some have sold all their holdings and exited the scene, I believe they are a minority. New bitcoin users are buying and gathering small amounts, that's tiny amounts compared to the large holders. Large holders still have lots and newbies still have too few.
Do you think major players are quietly accumulating right now?
I would think so. I base my optimism on the diversity of investors from the bitcoin auctions. Major players are certainly interested and there are MANY of them. Most of these investors aren't buying from exchanges, it's too slow. There are 3600 bitcoin minted everyday by miners. I believe a large portion of these minted coins are sold to these low-profile players.
the distribution of the base of the people who are accumulating Bitcoin is becoming much much broader
This is Bulls and a diversified base of new buyers coming in.
