Buying Ether Hashpower on Hashflare

I am small time investor in Cryptocurrency. I like to diversify. I hold few cryptocurrency and then i mine using hashflare, sun-mining, minergate. Going to try CCG Mining Soon.

SHA256 - I currently Run 18 TH/s SHA-256. Here is my story:

1. Purchased 3.3 TH/S on 22nd Sep 2017.
2. Added 2.2 Th/s in October 2017.
3. Realized Reinvestment can give you higher returns, switched it on in November.
4. Purchased $1000 SHA256 in Dec. 4.8 TH/s
5. Reinvestement added 7.7 TH in 4 months. It Rocks. Planning to disable after 100 more days.

DASH Mining - I made one mistake and Hashflare should return everyones money on DASH Mining. It really is bad. Purchased 470 MH/S on Hashflare. THe problem is i am not even going to make 0.1 Dash which is minimum withdrawal limit in a year.

Ether Mining (ETHHASH) - Since I know Ether has been doing good lately and its mining is more profitable as compared to SHA-256. Purchased $400 worth Ether mining contract on Hashflare. Going to add few more in following month.

Looking forward to buying $500 worth Zcash mining on CCG mining. and $ 500 worth ETH mining Next month. Have already exausted quota of this month.

Give me some insight how i can improve this income. Keep upvoting.. Thank you..
