Like someone DCA'ing every 2 weeks however holding off on putting in larger sums until they have mastered non KYC?
If you're DCAíng and don't want to do KYC just send your BTC to your self custody wallet.
Some exchange allow buying with limited amount without KYC so I think there's a way.
If you're holding your BTC on their platform and not doing KYC however, I won't be surprised if someday they enforce it and it might involve freezing your funds.
