Nobody gives us the earnings we deserve. They are always trying to make a problem
Actually you should never store any coins in exchange-wallets anyway.
You'll always get your airdrops and if the exchange gets hacked or shuts down you won't lose all of your coins if you store your coins in a cold-wallet with access to your own private-key.
Many people lose their keys and wallets because they're lazy, not doing backups etc
Or lose it due to some natural disaster...or someone hacks THEIR computer/mobile phone
So solution is to use your own wallet, but also put much more energy into keeping it safe,
which is hard for not tech savvy people
