How much you should invest in cryptocurrency as a beginner  depends on your financial status. If your financial condition is good then you will have one type of amount and if your financial condition is bad then it will be another type. Because according to the financial status of a person, his ability to take losses depends.  But one piece of advice I would give to the op is that everyone be it a beginner or a professional should invest in cryptocurrencies as per his/her ability because crypto is profitable without efforts but on the other hand it is high risk. So just as a person can profit a large amount quickly from here, he can also lose a very large amount quickly.
