To be honest, Bitcoin is not for everyone. Bitcoin is for everyone only if they use this as a payment channel or do not expect any good returns from it. People will low capital always end up losing money by investing in bitcoin because of their poor money management. People can make a profit out of Bitcoin only if they have good money management skills. If you invest $10 in Bitcoin, you should forget about this money. But people invest $10 in Bitcoin and start checking the price every day and check what is their position at this moment.
People should understand that Bitcoin won't give you profit overnight. We don't know how long it may take to give you a good return. Bitcoin is for people who have patience with their investments. They have to wait with their investment instead of checking it every day which is not possible for everyone. A person with a $3 average income a day cannot invest and forget about it.
Yes this is the big fault of Bitcoin investors that they hold bitcoin longer but wish to earn lots of money in a day due to which their emotions increase which will force them to do something worse that will just spoil their money. Market fluctuations will put wrong impacts on your investment if you get fear about lower price so don't be afraid and trust that Bitcoin will reach to your desired value.
Bitcoin holders should not think emotionally because they have to know about the fact that Bitcoin increase will take longer so regularly checking the price will just put you in a stressful situation. If someone invests in Bitcoin then he should think that taking profit before four years is not possible so by remembering this he will not think emotionally and will be ready for every condition.
