There are so many coins in the market and new ones keep coming which we need to understand that we can always buy and hold to try to earn some profits from them. Selecting a particular good coin from random of bad or scam coin can be very difficulty and we need to be wise when making decisions about what coin to buy and what coin not to buy. We can always make money from buying good coins but the problems comes in when we don't know how to identify good coins in the market. If we still want to make money then we have to be prepared to join coins or community that would keep updating us on recent new tokens to buy.
The difficulty of selecting good coins among scam projects can be solved if we study for it because nothing can come without using our mind and hard work. If we want to be successful from crypto investment then first of all we have to give time to make a thorough study that will aid in our decision taking ability and we will not be trapped into scam projects.
A person himself cannot predict the good and bad project therefore he should take help from his fellows who are experts in this field or should join some groups in which there are complete details about a project but one should not completely rely on YouTube videos because sometimes they are sharing wrong information.
