However, many people use other types of wallets, such as the Meta Mask wallet, paxful wallet, Coinbase, Ledger, Electrum.
But among these, trust wallet is the most convenient to use.
For most binance users trust wallet seem to be most convenient because it structure shoulder all manner of altcoins and that's where the deception for convenience comes in but what about security-wise have you given a close thought on that.
I would not say that keeping funds in a Trust wallet is safe as it is also owned by Binance. However, if there is a person who keeps funds in binance or on any centralized exchanges, then he can move these funds in trust wallet and by doing this his funds will be much secure as compare to leaving them on Binance.
Later on, when the person is used to the decentralized wallets, then he may move some of these funds to unstoppable and other better wallets. Of course, a hardware wallet is better than all of the wallets but until you don't have a hardware wallet you have the option of an unstoppable wallet and a trust wallet for storing altcoins.
