Simply put, someone who wants to invest in Bitcoin needs to think carefully about the risks and use one of the methods for their investment whether it is DCA or lump sum, and set their investment for the long term, to make sure that they can get better returns from it. Because most people only know that Bitcoin can give them profits, but they invest with the wrong approach - they invest in the short term and tend to be like gambling. An investor should think carefully about their decision and invest using their discretionary money or a few percent of their income continuously - and they need to hold it for the long term until they can get profits.
Those set of people only care about quick profits and only invested because of how they heard people making money from it. They believe they can just come in and make a quick profit without really caring to understand bitcoin investment properly and when it doesn’t end well for them they are the ones who go on to spread negative words about bitcoin because they didn’t carefully plan their investment. There are ups and downs in bitcoin investment as the price will appreciate and depreciate so to beat the market easily one should focus on long term investment and accumulate bitcoin using DCA strategy that way you are eliminating volatility of the market from your worries and since bitcoin has proven itself over the years long term investment is the best for you.
