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. By so doing you're not easily taking by surprise on any misgiving that may arise about a portfolio you have investment with.
Another gateway to keep abreast is to get connected as a member of an active crypto community or platform. Having membership of different communities is an added advantage but make sure they are a genuine platform with a good history just like bitcointalk.
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.
I'm not considering myself a newbie anymore, but I'm always not satisfied with the knowledge I have with regards to crypto. As a newbie, be always hungry for knowledge like those successful businessmen right now. They're always reading books that will give them information into something that they're excelling with.
Connect as a member of an active crypto community. We have already this forum as a platform already where people can just connect to each other, learn with each other, and possibly earn with each other. I don't use Reddit TBH, but I guess there is also a huge crypto community out there who are sharing information. Twitter? Just avoid that one IMO.
I know that diversifying your money is always a good idea, but instead of just investing into cryptocurrency, it would be better if you will diversify it into different asset classes. I mean invest into cryptocurrency, but at the same time, invest into stock market, bond market, precious metals etc. I don't recommend investing "ONLY" in cryptocurrency if you're a newbie. Yes the reward is high, but the risk is also high as well. Spread your investment, but not spread on different crypto coins because it will just have the same risk. If you invest in different asset class, the risk would be lower as some are less volatile than crypto.
