This has been an ongoing process basically this entire year. I have been keeping a close eye on several markets, and it shows that you see regular dumps accross various exchanges that hint at being an old/semi old hand. I like how even after these dumps, while they can instantly dump the market down with like $300-$500, the demand is pushing the price back up to the levels the dump has started, and that almost each time. All these dumps look to have been well thought out, and not just blind dumps where whatever entity is unloading thousands of coins in just one go.
