First, you have to accept that no matter what will happen don't lose hope because once you invest the risk is there. Crypto price is volatile we cannot say when it will go up and when it will go down. Second, research more about the coins that you are interested in, I will suggest investing in those coins that are in the top 20,50 and 100.. And also follow their social media accounts for the update regarding what is happening.
This is useful guys! Importantly, besides having fun, you should learn the knowledge, master skills, and gain an understanding of the market. Do not invest in the market until you believe you have enough understanding of it. If you invest when you're still unsure, it's more likely for you to lose your capital! Be wise and careful!
