I am not going to sugar-coat my words to any newbie, if you cannot deal with volatility; if you cannot handle losses, then quit if you want to. There are a thousand and one other kinds of investments that are more stable and less riskier than crypto. Bitcoin is even a better option for newbies but there are still risks. Just like op has mentioned, if you cannot stay committed and disciplined, go for other options that suit your risks tolerance instead of holding on to something your mental health can't handle.
And we can say that crypto is not for everyone, not for the faint of heart, that person who can't even go and complain about the decline of price. So it's really like we need to go to school and learn everything from scratch.
So patience is the key here, for sure we have heard this before, but that is the truth. So really need to have a lot of it inside so that there will be no mad swings like in one day you want to sell everything and quit and then the next day, you want to stay. Everything boils down on how you can really handle and yeah, it's all mental games for us.
