A quote from the research conclusion
However, this acceptance and interest comes with conditions. Merchants want to
see the full integration of cryptocurrency into existing POS/eCommerce software
and hardware. Moreover, they are interested in instant fiat payouts or flat value
token conversions. This will not be possible if barriers like high transaction fees,
cryptocurrency market fluctuation, high transaction times and lack of integration
with existing POS/eCommerce software make business owners feel uncertain about
adopting cryptocurrency in their businesses. Overcoming these major hurdles could
certainly usher in a new era for cryptocurrencies.source.
