As newbies when investing in crypto don't be satisfied with your leading knowledge attainment about crypto, endeavor to continually do research on the crypto asset's you have invested on as it would aide you on a trajectory course about your investment's.
What you mean by primary knowledge is probably the basic knowledge to invest or trade in crypto. It's true, if you only rely on the basics and don't develop your knowledge, you will surely be less than optimal in getting the benefits.
Because if you become an investor in the field of crypto, it is very obligatory to continue to do analysis, research, and learn about crypto, especially the crypto you are investing in. Because if you don't continue to dig up all the knowledge and information, it will definitely be difficult when you want to get benefits. But I'm sure, if someone is serious about investing in crypto, they will always continue to research and analyze the crypto they are investing in. Whether it's a beginner or an older one, because all of these people will definitely work hard so they can benefit.
As a matter of fact, it's very unsafe to depend on a single coin. In otherwords, invest into more than one token by spreading your investment into potential coins but be careful not to invest into pump and dump coins. Above all, make sure to maintain risk management in which ever crypto asset you are investing in.
It all depends on the decisions of each person who invests. Whether it's investing in lots of crypto (altcoins) or one of the highest quality cryptos like bitcoin, everyone will have a different opinion about this. Because when someone invests in crypto, they definitely have the same goal, which is profit. But there are various ways to get it, such as by trading in the short term, or trading in the long term. So your opinion is also true, for crypto investors who have a habit of making profits the way you do. But that's not necessarily true for all investors in crypto.
