Rule of thumb in trading any markets: Do not trade what you cannot afford to lose. So, it means it depends from one trader to another! Good luck fellas! May the odds be ever be in our favor!!
Yes it is rightly said that only invest what you do not require immediately in crypto markets or afford to lose the max. Another couple of things is that if you are weak heart person or cannot be patient then do not trade or invest in this market. Do invest in few coins and diversify rather than investing in a single coin.
