You should only store your coins in exchange if you are a day trader. But only temporarily. Your core profits in terms of ETH & BTC should be moved to a physical wallet. Trust me, there are no other exchanges as trustworthy as keeping it yourself physically.
Of course, with 2FA activated in Binance it is very safe but as long as your token amount exceed 4 digits (in terms of USD value), do invest in a physical wallet. You will not regret.
