If I already KYC'ed at a service, does it matter if I continue using it?

Privacy regarding LN withdrawals on CEX

The only bad aspect I see about CEX is that you have to do that shit KYC, no matter how you withdraw.

KYC is bad not because of the gov/ taxman, but because your data is in 3rd parties several hands and you don't know where will end up.

### If you never sell back your BTC for fiat on those CEX, there's nothing to worry about gov / taxman. FUCK THEM.

I explained more details and aspects in several of my guides:

P2P exchanges are good for example when you want to:
- not giving away your KYC data
- want somebody else to pay your fiat bills and you pay them BTC
