The greatest life lesson I learnt is that don't invest any money without any good knowledge and also don't take part in the ico which doesn't have good potential or it has no road map.
So from seeing the full content of the ico and the coin we should ask about the coin to 5- 6 people who had good knowledge on crypto coins so my taking all the opinion and then also we should do the opinion and then only we should invest so we can have a good return.
The greatest lesson i learnt is don't go and investment in the ico or a cryptocurrency and also mostly don't invest on the crypto which are Indian coin.because Indian government are not regulating the Bitcoin so the price will not spike up.
Thanks for Reading
