Starting immediately and as part of an effort to increase transparency by providing as much information symmetry as possible, Coinbase will be using this blog post as a pilot to communicate assets under consideration for listing in Q2 2022 (April 1st, 2022 to June 30th, 2022).
This is going to reduce volatility a bit , but now people will speculate about which assets are going to be listed in the consideration lists. Then, which will go from consideration to real listing.
There is no way to "stop" this volatility, neither the problems related to insider information.
If someone discover that an asset will be listed there (or go to the consideration list), then he can make money out of it.
Coinbase exchange introduced new analytics tool called Coinbase Tracer that is created to deal with compliance issues.
They are now using risk score for addresses, looking at connection with exchanges, custodians and if no kyc is connected with specific address.
Addresses are connected with real life entities and used for signaling about anti terror financing and AML flags.
According to one screenshot they posted it appears that every address that is no-kyc connected with real life identity now has medium risk!
It is a good idea to avoid using that in your own addresses. It is very likely that coinbase will keep IP logs of searches.
