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.

Theres more bigger spikes on exchange rate sometimes.
