1) First of all you need Bitcoin and Ethereum wallets. I prefer to use http://blockchain.com because you will have both wallets in the same account, but you can use the wallets you like.

2) You need to have at least 0.002 BTC in your wallet. I would recommend to start with 0.01 BTC or more, which would give good money from the first exchange.
3) Then you need to exchange 0.002 Bitcoin to Ethereum using exchanger https://bitexchangers.live/
right now at the rate 0.002 BTC - 0.14 ETH
How to exchange here:
4) Now you need to exchange 0.14 Ethereum to Bitcoin using the exchanger https://changelly.com/
right now at the rate 0.14 ETH - 0.0073 BTC (Click "Exchange" button in the window on the main page of the exchanger to see exchange directions)
5) So you earned ~ 0.0053 BTC (about $220) profit per one cycle of exchanges!
6) Repeat this procedure 82 times and your profit will be about $18000! And the best thing is that you can repeat this unlimitedly! If you start with a larger amount of BTC, profit will be higher in each cycle.
The above exchanger's links are my referral's link. Exchangers have referral programs, and I get a small % from each transaction if you do it using my links. You can do the exchanges without using my link, but it will help me as gratitude for unveiling this secret!
Exchanges rates can change every day, so earn now when you can!
