how to implement earning point in website using Angular2+

You need to create Betting site ( i hope you understand betting site otherwise you need to google it). After registration on site (by facbook/google/Form) every user got x point lets say 100 points. Every Match needs some point to participet that can be deducated from theirs virtual point accounts. 

 

There are less information about the logic use for point calculation so you need to query from your instructer or search  on google for Betting points calculation methods

 

one more thing you need to access webservice for Match catalogs. it may be in Rest / WSDL 

so you need to understand the response formate then to build logic arround it
