Here is the last review I did on Genesis Mining:

I have re-invested everything into upgrading my BTC contract during the pre-sale of BTC contracts.

Here is the link to the last "BTC pre-sale" post:

You can read my comments in that post about my future plans to upgrade again next year.

For myself, mainly because of the rise in BTC prices, the BTC mining contract has been the best for me.

Have a great weekend!
Steem on,
Mike
