I think every member of the bitcoin community should ask themselves the question, what color is their current bitcoins
I think every Bitcoin user should have color blindness in that matter.
The favorite mantra of bitcoin maximalists "1btc = 1btc" does not work because the coins in the open blockchain are not fungible.
I strongly disagree.
There are abundant bitcoin buyers and sellers who are willing to exchange bitcoin without questioning the coin history at all. That alone should be enough to consider it fungible. The fact that some companies enforce a view in which some coins are worth less, doesn't mean they really do, because there are people who don't buy this view, and still are willing to buy / sell them for the same price.
If this is the case now (due to the imperfection of automatic blockchain analyzers, gaps in the legislation of different jurisdictions and local weaknesses of regulators) - this does not mean that it will always and everywhere be like this. Of course, there will always be more loyal jurisdictions that will be color blind in the matter of bitcoin color differentiation. And I'm talking more about the real risk of such a separation in the future than about a fait accompli in the present.
Although it seems that some centralized exchanges even today will automatically block your deposit if the incoming bitcoin had traces of passing through the mixer in its history. The deposit will be unblocked after you document the legality of the origin of the funds, show a certificate of income.
