Many of them said to keep Bitcoin in Binance Account, Ku Coin Account, Trust Wallet.
Wrong,
Who are those recommending these ones to you, are they really bitcoiners, these are exchages except for trust wallet, don't leave your bitcoin with exchages else you will one day discover having the same experience the users of FTX, Mt Gox exchanges have and loose their asset completely without having them recovered.
No, you can't have access to yiur coins anytime as you want, they are centralized exchange, having similarities with banks, they have censorship, your money with them is not your money, it's theirs because they have custodial exchanges, they are not recognized as wallets but accounts.
this are the best i could recommend for your use.
