Here is the biggest problem with cryptos that no one is focusing on

If you want to sell digital goods or if you need a notification on your shop that client made payment you have to use a third party or a node  or a smart contract

Not one crypto solved the problem of allowing merchants to sell their own digital goods easy

To deploy a smart contract costs money each time you need to update it and you have to create a dapp for it

To host a node costs money ( hosting fees )

To use a third party costs money ( fees )

What's the point of a crypto if i can't use it as a merchant easy and without extra fees ? I could just use paypal or credit card processing ...

We must solve this problem

The merchant should easy copy/paste a code and put it in his html .
