There is one important thing you forgot to mention.

What matters for fees is not how many addresses you have, but how many inputs you have.

Let´s suppose you engaged in many sig campaigns and you received 0,0005 every week for 20 weeks. You earned 0,01BTC, however you will have more than 20 inputs on the same address.

Every transaction made from your address will now have cost based on every input, individually, when you want to move them.

That´s why it´s important to consolidate your small inputs when fees are low.

If you consolidate your 20 0,0005 BTC with 2 sat/byte, it will be much cheaper than making a transaction now for 20 inputs with 60 sat/byte.

Take a look at LoyceV guide about it:
