You can really daytrade cryptos if you're keeping them off the exchange unless someone knows something I don't.
But I have been thinking about this a lot and will probably start moving a lot to wallets.Bitcoin is easy but not all coins are as easy to move. This is the biggest hassle of dealing with Cryptos.
You should:
Use a Email Address that is as random as your key and use it no where else.
have a long random password.
2FA on your phone with Authy.
And if you can move what you plan to hold long term to cold storage and have backups of that in case of fire and theft.
