Are you sure that this is a promising coin?
You said that Zero coin has been mined since 2017, so this project at least has been existed since around that year, right?
How can you say that this coin is a cheap promising coin? If:
- It has a small trading volume even has been traded for several years.
- It is not listed on top exchanges even has been a long time
- The price drops very significantly far away from the ATH
- There is no significant progress and development of the project or coin even after several years

Well, I am personally will be very careful when going to choose this kind of coin.
In fact, you are part of the team and this is not kind of a good advertisement or promotion method
