There's this advice my dad gave to me some years back. He called me and say, "my son, if you want to archive success in what ever you do in life, learn to take advice mostly from those that have archived success in the area you are seeking to be successfull. learn from the mistakes of those that tried and fail but don't allow them discouraged you. "
Your father's advice is valid but it might not be the case at all times. Sometimes, you can learn from people who are not successful, but it all depends on you to keep learning. The person who introduced me to Bitcoin was not a successful investor. He introduced me to the sector, and I took the time to verify what I learned and went further to acquire more knowledge.
Some people wanted to invest in Bitcoin but took the advice of some one that have not invested into Bitcoin and the person convinced them not to invest.
Some people invested already and where holding their coins but a non investor adviced them to sell their coins and they sold off quickly and regret after the market boom when they have sold off.
There are fudsters everywhere, so you should always verify before you make any decision. Your ability to verify the information you get from individuals and news outlets is what makes you a mature investor. You should be responsible for your decisions because they money belongs to you.
What is the best advice you got from your parents that has always been a tool of reference through your journey in life?.
My mother has always told me to enjoin the right and forbid the wrong. I have learned to always be upright in my quest for financial stability.
