The technology is there but there is not enough liquidity to use decentralized mixers, so using centralized mixers is faster but it requires trust in these services and unfortunately few mixers are trustworthy.

I can say that jambler and mixero are the best currently but due to the governments war on privacy services in mixing services it is rare to find a continuous mixing service for years without problems.

The best solution is to use Monero to break the link between your inputs and outputs.
