First off, either a beginner or not, the question is how much do you have?Bitcoin has been in existence for a long time now but there are some folks who are yet to be exposed to it.
For someone who is new to the world of cryptocurrencies specifically bitcoin, how much would you consider to be right amount for such individual to invest?
You can't give what you don't have. Same here, you can't invest an amount you don't have.
Generally in business i advice people to invest an amount they know they can cope with if loss is experienced.
So, I advice that only an amount that you can afford to loose is what you should invest.
And don't invest a fund you can't afford to let fallow for a period of time because of the volatile nature of bitcoin, you might be required to wait for the coin to recover in case of a dip.
