Step 1 is to buy BTC with USD [from
https://www.coinbase.com if you are able to, or somewhere where the price is similar to $429].
Step 2 is to sell those same BTC for paypal USD [at
https://www.satelexchange.com].
So basically you can buy 1 BTC for $429 and sell it for $466. The profit is around $37 per BTC.
method is good. but I dont getting how we can sell 1 btc for 466 dollars. although BTC price is only 440 dollars?
