I believe one of the major setbacks of the present crypto space is a lot of new projects are focused on providing the fastest easiest crypto coin to be used for payment purposes and transactions however considerably lower effort is placed on the vendors who are actually going to be accepting payment in form of cryptocurrencies because what is the use of having a crypto payment card full of money that you cannot spend.
Whitmore payment gateways a inform of PayPal and the likes accepting crypto payments from multiple coins without necessarily issuing their own coin then there will be better adoption of cryptocurrencies by both business owners and customers.
You are right there are so many of them, but they are positioning themselves when the market grows for cryptocurrency payment, cryptocurrency payment will be adopted in the future, it is guaranteed to be, and it always pays for a project to be in the market, when that time comes.
