If you hear someone say: "Buy quickly, the currency is going to rise
What is their evidence?
Are they really investors or just promoters?
Have they reviewed the project or just heard a rumor?
Currencies do not rise because they are about to 'explode',
They rise if they have a strong project, an effective team, a clear plan, and the entry of smart money.
Before you buy:
Understand the project.
Monitor the volume.
Check the market timing: is it rising? falling?
