Just don't store in an Exchange or you don't have full control to make withdraw your funds or restrictions.
If you want to store your bitcoin invest in security in bitcoin too if you don't have a budget yet go for the Hot wallets still with the electrum or Exodus. We highly preferred to use the Cold wallet or the hardware wallets to make sure your funds are safe.
