There must be some checking prior to PRs, so we need to have a multi-stage Github Actions file in which we:
[ ] Make sure our code is Linted properly.
[ ] Make sure our code could be built.
[ ] Run all tests, showing coverage.

Based on #3, we have some proposals for new Entities (At least two). Now we should add them with their migrations to the project:

[ ] Add entities.
[ ] Add migrations and test them.
[ ] Add a simple DBActions class.

We need a job with configurable intervals to fetch the price (and possibly other data) of some specific coins. These coins are also configurable and could change by restarting the project. We don't have a policy for deleting coins yet.

[ ] Setup the job, add the required function to DBActions, and save the entity.
[ ] If the coin meta-data does not exist, save it in the same job.
[ ] Test the working apps, don't forget about the unit tests :)

The project should be able to connect to different DBs, preferably with TypeOrm.

The project must support config, via env vars or Yaml configs.

In this task, we want to have an intro to the CoinGeko website and its API features. So we have to:

[ ] Explore different APIs, and play around with some API clients.
[ ] Write a simple fetcher, to fetch some Coin's data (especially price!).
[ ] Propose a data schema for storing coin data and another for storing its price.
