This sounds like a dumb question but after seeing what happens with FTX i really worried about any centralized company i am using for my crypto. Trust multi wallet is really a decentralized wallet? I am using a multi wallet in trust wallet that has BTC, ETH, BNB, dot and most other blockchain which i can access through one mnemonic phase. So if something happens with trust wallet company and their apps become inaccessible then how i will be able to retrieve my btc,dot and other blockchain assets by using that one multi wallet mnemonic phase?
If you are skeptical about the trust wallet, there are other options besides this, mate. If you have a hardware wallet or trezor that's better, now if you don't have that, there is still a metamask wallet as long as the private key or seed phrase that you will use is safe.
Then google is there so you can find legitimate and safe wallets, then electrum is also there if you store bitcoin in the wallet.
