I have started using from network for transferring my USDT tokens instead of transferring it on the ethereum network between exchanges because it literally saves me 2-3 USD per transaction.
Dogecoin transactions are cheap. However, I think the answer can be always Googled: there is no sense to ask this question here. Forum users are those guys, who are not professionals. Time can be simply taken to get this stuff and pick the needed altcoin for operations.
