If you have Genesis send you the payouts in BTC you have the option of sending you payouts to :

• your SteemIt (power up address) which will convert it to STEEM Power
• your SteemIt (STEEM buy address) which will convert it to STEEM
• your Coinbase (wallet address)

I am currently sending my Genesis Mining (Bitcoin) payouts to my Coinbase wallet. I let the payouts accumulate there until I am ready to make further transactions. Coinbase currently provides wallets for Bitcoin, Ethereum, and US Dollars. Coinbase has worked well for me. I have never had a problem with micro-payments. Some of my recent transfers to Coinbase have been as small as $0.17 USD.

Steem on,
Mike
