I've asked many people, big and small, which wallet bitcoins are the safest to store long-term.
Many of them said to keep Bitcoin in Binance Account, Ku Coin Account, Trust Wallet.
Lol, who are these people? Based on the answer they gave you, I would suggest you not to listen to them or ask them about any crypto related issue as they are obviously ignorant.
Bitcoin enthusiasts who took an interest during the last bull run. They don't know anything about it, except that you can trade and make a profit without knowing the difference between wallet and exchange.
