1: json: cannot unmarshal array into Go value of type main.Catcher or 2: json: cannot unmarshal object into Go value of type main.Crypto4

I was searching relevant posts regarding error "json: cannot unmarshal array into Go value of type main.Catcher" or "json: cannot unmarshal object into Go value of type main.Crypto4". These two error messages are linked to the same program (depends on when I change structure). Actually I have to write/display data on HTML file which will linked through local host port 8080. I could not understand where is the problem I have shared my code and link is attached here.
https://play.golang.org/p/DLOdEGS7hmG (I have quoted main problem with my code instead of write down all the code, means another function where I presented json data through api and it works good, but presentation of data on html file is the problem.
I have created slice like var collect []Crypto4 inside the function and unmarshall data through this variable, but still getting error and html file is not displaying data, instead of getting error which I wrote above in title. It would be so nice to guide me and point out the problem with possible solutions, thanks.

You are declaring your struct as []struct and then using it as ”var collect []Crypto4” effectively doubling the arraynes 😉
See this: https://play.golang.org/p/Q3RzNddeVVT
And on a side note: Please check your errors – especially if Things doesn’t work – a few err != nil along with fmt.Println’s will save the day 😊
