This is the main function of the crypto package. If you want to retrieve ALL coins then do not pass a argument to getCoins(), or pass the coin name.

Please note that the doSNOW package is required to load the progress bar on both linux and macOS systems as the doParallel package does not support it.

Examples

# NOT RUN {
# retrieving market history for specific crypto currency
