There are two ways of how to cope with this problem. You can either switch to another cheaper chain (Tron, BSC) or you can pay less, but you will have to wait more time.
Any other chains aside bitcoin blockchain are not actually used to store bitcoin, bitcoin is stored on bitcoin blockchain, others are just tokens pegged with bitcoin. It will be best for the person to continue using the bitcoinnwallet and making use of bitcoin on-chain for transactions. I will still prefer to make use of low fee and while the medium fee of 5 sat/vbyte is not high at all.
