I usually advice people, to invest what they are afford to loss. it doesn't matter how much you have, as a beginner you can start with a little investment and try to understand how the network works. as time goes on, you can continue to increase your capital.the most important thing to understand before going into investment is how to secure your asset, protecting them against scam or loss. if you have a good idea about this, you can decided to invest what ever you have.
everyone who is into cryptocurrency investment supposed have known that is supposed to invest what we can afford to lose, meaning that with cryptocurrency investment you can make a profit and you equal loss and when you loss you don't to be depressed, so it's encouraging for someone to invest with its spare money not the money that sustained him or she, so we should be try to understand the basics concept of investment and know the amount of money we can invest in cryptocurrency and when lose it and it will not be painful to us, mostly we that knows the implications of investment.
