Please stay away from those who only talk nonsense like "Bitcoin is a scam", "the crypto world is garbage", "Bitcoin will go to zero".
These people either have never made money or do not want you to make any. They cannot understand the trends but love to pour cold water on everything; they have never truly studied blockchain but pretend to be more professional than anyone else.
While US institutions, global governments, and the World Bank are quietly increasing their holdings, they are still in the break room comforting themselves with "Bitcoin is about to crash" because they feel powerless to change their lives.
You do not need to please these people. They only hope you remain as mediocre as they are and then laugh at anyone who tries to change their fate.
Choose to stand beside the institutions, do not be dragged down by the frog at the bottom of the well. The real risk is not failing to invest, but never having the courage to start at all. $BTC
