My best advice is for newbies to always invest money that is left over or money that is in reserves because don't use money that is ment for solving problems or money that is supposed to be used for running the home to invest thinking that it will bring profit to you in a fast way that is wrong so people should always use Dollar cost Average (DCA ) or systematic investment which involves using a fixed amount of money to be used for the purpose of investing over a time interval which to me is cost and even economy friendly so newcomers to the crypto space should learn this because it will be helpful to them
