If you have lost your keys my suggestion to you is:

Make another account.

Your HIVE keys are everything on this platform. Without those keys you won't be able to withdraw any money you make. You won't be able to play any of the HIVE games which allow you to make money. You won't be able to access different platforms which may have better interfaces (like PeakD) or even apps that I've made no HIVE (like a secure digital file encryption and storage app).

As for making money on HIVE? Once you have keys to your account (this one or another you create) you need to be realistic about how much you will make on HIVE.

In my first month of actively using this account I made about $2 USD. Over time it grew but it has never been huge amounts of money.

Realistically about $45 USD / month is about as high as I would say is realistic for the near term on HIVE and even that is only with the help of the GLD community and actively participating in Actifit and Hive Learners.

If you need help creating a new account let me know ;)

I know shortcuts and the best ways to get new accounts :)

....although finding your current keys are preferable.
