Without knowing why people change their wallets, it’s hard to nail down a solution. But, perhaps a smart contract wallet whose access is controlled by an underlying wallet that can be swapped out may help. In any case, all transfers or smart contract execution attracts a fee. Even sending money between wallets.
I’m not sure. If that is their strategy they’re dancing on a razor. I mean, the market is pretty slim. Basically, you can get a pretty sweet gaming PC for the price they’re offering. And if you project the amount of games you’ll get and estimate the price differential with prices of the same games on a PC you might be able to uprate the specs a few times. I would say that a PS5 with a reasonable amount of games is probably worth a similar amount to a $1k PC.
