Anyway if it really happens then the answer to use a decentralized wallet like trustwallet.
I don't see reason they would say thing like this.
Trust wallet is not decentralized wallet, although its labeled as non-custodial, being a closed source is a huge factor that it should not be called as "decentralized wallet". Although it houses different tokens/altcoins for "decentralized" finance and exchanges but it still not a decentralized walllet.
