Working for me:
- using cold wallets // Ledger, use every time unique wallet for storage, use several wallets on same ledger
- diversify to several cold wallets // hide them on secure places
- using mixers // only if don't want store it, use it for buy stuff. All mixers are risky but it is working
- using virgin mined crypto // several services, small fees
- avoiding big exchanges // if need use main exchanges split it to several mixers and change it with virgin mined sevices
