I know that it takes courage to invest in bitcoin but it does not necessarily mean that they are coward if they are holding back. There are many reasons behind it. The most common thing is the money that they are going to use could their life or family savings and if they messed up then their lives are over so it is unfair to call them cowards because they are just being careful.

You are right, and that is a fact. If a person does not think about the impact of what we will do then defeat will be the answer. Someone becomes a coward like you say, because we all don't want to lose with our investment in bitcoin.
I think maybe is mean not a coward but a loser , because many of the bitcoin users who become a loser when they see the red market and panic sell their coins. It happens as it is now, where the market situation is in red and they sell some of their coins.

If cowardly investors then they will not take big risks by investing other altcoins in large numbers.

Its not about being coward. Its about investing wisely. Everyone here invest as per their risk appetite. Even Today's Crypto millionaire and Billionaire, they have also invested wisely and taken risk which they were ready to take.

They are being cowards because they think that their money will become loss or gone,i think these are the people who didnt know more about crypto,so i think they need to learn more about it ,so they have trust in their selves or about what they are doing.

How can you even say that and where did you find your confidence to say that? Well I don't think that would be an appropriate term to call someone who is in this system. You can't really tell someone that kind of word because it's very degrading. We should respect all decision that we're going to make and just like in bitcoin respect the users and investors.

Every young investor now a days is afraid of taking risks they want easy profit in short term, they don’t bother to study about the market patterns and just want small profits over night and this peoples regret when they lose all due to their no knowledge, these are the real cowards, for the one who are buying btc now are the most intelligent, they will hold the bitcoins and sell them once it reaches a new peak price no matter how much time it takes.

I wouldn't say cowards but safe players. They don't want to take risks because of the impending doom of losing everything overshadows their interest to invest. I don't blame them for playing safe but it is such a waste of a good investment to pass.

playing safe is not a problem, but the thing is that there are too many uneducated investors who have nothing else on their agenda than selling due to panic and complain on forums...
