Putting assets on an exchange is very risky. what happened to FTX certainly teaches us a lesson. we have no control over our assets. everything is owned by a third party. so it's better now we get used to storing assets in our wallets. if can't have a hardware wallet, an online wallet like Trustwallet is fine for a while too.
Trustwallet or Coinomi as a wallet that can be multicoin compared to storing assets on this exchange is more risky after seeing the impact of FTX which has become a new trend due to failure which eventually led to bankruptcy.
In fact, we are planning a long term investment, so just buy this hardware wallet, you have to sacrifice a little money to buy the wallet. For me, this is important and even if you don't want it, the wallet mentioned above is still worth it as long as your private key is responsible for yourself and not can store arbitrarily.
I myself believe more in hardware wallets and Electrum being a bitcoin wallet that is comfortable to use.
