One more case related to exchange which makes the members more worried. After a few days before Upbit experienced hacking, now IDAx is experiencing problems related to funds whose rumors were taken away by the CEO. and true to the OP's advice, don't deposit funds in wallet exchange, it's very risky. I only use wallet exchange when trading, after that I choose to secure my assets in another safer wallet.
In just a week, there were 2 news that made investors panic and now I have withdrawn all my assets to cold wallets because this is the safest way during this period. In my opinion, should only use 20% of the assets to make a profit and always research that exchange before making a deposit.
This year, a lot of exchanges like Idax, Binance, Upbit made many investors lose money and currently decentralized exchange is a temporary solution for everyone. Personally, I don't trust new exchanges because the risk is much higher than the old ones.
