Suggest online wallets for crypto

Hello mates, I need online wallet for my crypto because in exchanges I thinks coins are not safe.

For me Step 1 is to specify your criteria for assessing which is the best option. Here are 3 to get you started:

1. Security - eg 2FA + 3rd Party Authenticator + email confirmation (possibly two signatures)
2. Costs for trading / excahanging / buying / selling
3. How to get the CASH Out - I've discovered that this might be more important than getting the cash IN
