I scatter my bitcoin into 3 wallets. One to save with. One to make larger purchases or trade with and then a hot wallet for making small payments but like the second poster siad it seems less and less likely like bitcoin will be used as a currency if these high fees have anything to say about it.
If you mean other crypto I keep 2 wallets. One to save and one to spend. Lesser-known coins/tokens I only ever use one wallet since I wait to sell them at the right time.
