At times the ratio for the Bitcoin (BTC) price in $US to the BTC price in Euros is different than the exchange rate. When this occurs, use the following method to make money with no-RISK:

1. sell the higher priced BTC/currency pair
2. convert the funds to the other currency
3. buy BTC with the other currency

Here is a table of BTC/$USD, BTC/EUR, and the $USD/EUR exchange rate for the time period Monday, April 6th, 2020 to Friday, April 10th, 2020.

On Tuesday through Thursday, this method would be profitable. Here is an example for Tuesday, April 7th, 2020.

1. sell 1 BTC and get $7,176.41
2. sell $7,176.41 and get €36
3. buy 1.0084 BTC with €36

It is necessary to include the trading commissions to calculate the total profit. To use this method correctly it is necessary to have sufficient capital available.

Good luck with trading.
