If you don't have a hardware wallet then the second best option to safely unlocking your wallet (without having to trust them) is to use a wallet software which supports the WalletConnect protocol such as Trust Wallet, Atomic Wallet, Math Wallet...
This option will allow you to connect to your account and trade without having to expose your private keys. Kinda similar to how MetaMask works.
Thank you, my brother @khaled0111 , although this process was a bit of a risk but I tried it on Atomic Wallet with a few Coins and the experience was successful and I think that Binance Dex is safe they have created a Key store I enter through it and my coins safely so far.
As for the Trust wallet or Atomic Walt mobile application, you can enter through it without putting the seed, but its problem is that you must keep the application open and you cannot work on the mobile in the meantime and this is a bit annoying.
