Investing in Bitcoin is just a self determination and not by force to buy it. And it is not because a large number of people buy Bitcoin and that will also make others to buy, things are not working in that way.
And it is not surprising that some set of people are investing because they see their friends are also investing in Bitcoin. These set of people that come to the cryptocurrency industry with others' people thought they hardly stay long in the crypto industry because they easily get panicked if it doesn't go how they think. If everyone were to get convinced by their own knowledge to invest in Bitcoin, I have some confidence that they will hardly get panicked in the process of holding Bitcoin for a long period of time. It is people's opinion that some investors always follow, that is what always.
And this is why they always advise people to learn before investing, because from that learning you will know what are the objectives of what you want to do and you will know the investing will favor whether for a long time or short time. Though we all know that Bitcoin investment is always for people who are ready to invest for a long time, because that is the only you will get profit from the investment.
Honestly, with proper knowledge, someone will able to make proper decisions, whether their investment should be based on short-term or long-term investment. So, if someone wants to be really successful in bitcoin investment, knowledge has to come first, and that will really be a great help when making any decision.
