free CryptoCompare API and free CoinCap.io API crypto data api to show live Crypto prices
So, you take the info from a free API and want to charge $10 for the service... I don't know buddy. It should be free and if you think you are really offering a service, then charge it in $100 and not in $10, because web develope isn't an easy job, even if you are taking the data from APIs, to develop a tool like the one you offer isn't an easy task at all.
Even if they use free API has the right to charge for his coding skills. Still, not everyone can use API although it is free, programming knowledge is required.
To use API and load the Live Price & Data requires coding and we have done.
so after uploading the relevant files to your host Charts will run once we do it.
And you don't need programming knowledge.
You're right! The price we announced is only for a month.
So, it's only possible uploading and installation files from your side, I can't buy all files and install it on my server by myself. So, any hosting changes, I must contact you to upload and do all things again. What after six months or one year, where to find you? will you still be here and you want to do it for the same $10? Maybe I know something and I plan to customize this script but it's not allowed. You haven't admin panel there, why? If you know programming implement this staff then any noob can use your script.
Your demo
https://walleteum.com/data/chart.html is not fully functional. When I try to go on any of coin page, got Error 404. I guess you are successfully loading data from API's and you are satisfied but it's not enough if you want to do something serious.
Now it's not worth more than $10 and the question is who needs it.
My advice to you, finish it completely and then can expect buyers and higher price of course. For example, check this
Wordpress plugin. Okay, it is WP but checks functionality.
