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.
