It is not only better to do our due diligence, it is our only option, anyone that invests in an asset following the advice of someone else is making a mistake from which they may never recover, because even if they were to succeed and make money with that advice, they will forever damage any confidence they may have had on their abilities and will become dependent on the advice of others.
Then for the rest of their trading careers they will look for investment advice, instead of looking at the charts and everything surrounding a project and decide on their own if they want to invest in it.
Yes, of course it will be very difficult to recover from losses from investing by following advice from other people and also we have to ask that person for advice again about the investments we make and in my opinion it is not very good for us to depend on other people's advice because we will not be able to develop if we continuously follow people's advice about the investments we make.
