the fees are high if you move a few tens of dollars, in proportion to a transaction of 20/30 $ you pay 10/15% of the value in fee. the important thing is to avoid making micropayments with Bitcoin, to make micropayments the altcoins are better
If people still wants to make small transactions with Bitcoin on chain they can still do so but they have to lower their transaction fee. Using altcoins for smaller transactions does sound good but it's not always applicable because there are services and merchants that only prefers to accept Bitcoin.
Tactically you advise to always convert Bitcoin to altcoins whenever there's a small transaction to be carry out?
Use Lightning.
Or monitor the network until the fees starts to go down.
