With the development of blockchain analyzers, including the use of artificial intelligence technologies, and the general development of the digitalization of society, bitcoin may in the foreseeable future be divided into three large clusters:
1. Bitcoins on verified bitcoin addresses that are uniquely associated with the identity of the owner, let's call them "white" bitcoins for definiteness.
2. Bitcoins without any history of miner rewards, let's call them "gray" bitcoins for definiteness.
3. Bitcoins with a dubious history, including those that have passed through the mixer, let's call them "black" bitcoins.

I think every member of the bitcoin community should ask themselves the question, what color is their current bitcoins, and what color bitcoins would they like to own when the difference between bitcoins of different colors becomes really significant?
