I like the idea in the article that big wallets need to be monitored. Such websites should actually be easy to setup by fullnode operators.

I see the following relationship:

* If large amounts of bitcoins flow into the wallets of the big exchanges, then the danger of a price crash increases.Why else whales move their Bitcoins into Exchanges?

* If the wallets of the exchanges become smaller, a price stability is to be expected. Bitcoin buyers are backing up their bitcoins in their private wallets. Means less selling from big whales is to be expected.

I see a new trading indicator I am wrong or how do you think about it?
