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.
Well, you have a good point though. That is, if you think you can’t be comfortable anymore investing in bitcoin because you can’t deal its volatility nature. However, if you can still stretch your patience and find ways on how to make it better and minimize the risk brought by volatility, then quitting isn’t the best option.
Bitcoin is always a high risky investment, one should be aware of it prior to investing. So if you think you are one of those weak hands who get easily panic when the price seems highly unstable, then I suggest get rid of bitcoin while your losses are still manageable.
