1) You need Bitcoin and Ethereum wallets. I prefer to use https://blockchain.com 

You can use all other crypto wallets and exchanges  to send and receive funds not only blockchain wallet . 

Absolutely all crypto wallets and exchanges are suitable to receive and send funds.

2) You need to have at least 0.003 BTCat your wallet now. 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 BTC to Ethereum using exchanger https://leadingcrypto.top/ 
right now, 0.003 BTC ~ 0.225 ETH ( here you can see the exchangers license )

How to exchange here:

1. Fill the form and click "Continue Exchange".
2. Fill the next form, click "Become Exchange" icon.
3. You will see the BTC address where you should send the specified amount of BTC. Don't forget about commission for transaction in BTC network!
4. You will receive the Ethereum after the 1st confirmation on BTC network; it takes about 30 minutes

4) Now you need to exchange Ethereum to Bitcoin using the exchanger https://changelly.com/ or https://changenow.io/.
Right now, 0.224 ETH ~ 0.0135 BTC 

5) So you earned ~ 0.0105 BTC (about $300) profit per one cycle of exchanges!

6) Repeat this procedure 50 times a day and your weeklyprofit will be about $100 000 ! ! 

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!
