So I am looking for a payment provider that accepts BTC and Altcoins
(LTC, XRP, ETH ... maybe XMR)
You need to answer a number of questions:
- What is your technical expertise? Do you want Self-Hosted Bitcoin Payment Processors or Hosted Bitcoin Payment Processors?
- The price allocated for development and security?
- Number of clients per day and number of traffic per day and month?
- Required fees and do many customers use the site?
After all we can calculate the cost economics and choose the right option for you.
CryptoWoo is the worse option you need to pay $34 - $99 per year
