For sure there is nothing wrong having arguments even though sometimes some people can be too entitled to their own opinion without giving a second thought to what others are saying, for those you are referring to that are using their mouth to accumulate we don't have to worry about that and think more about our self and our achievements because we are all responsible for the consequences of whether or not we invest in to Bitcoin, Bitcoin is not begging anyone to invest in it for it to be called Bitcoin.
It is a waste of time to think if people are accumulating bitcoin or not, because it is none of anyone business. Whether invest or accumulate or not it is not anyone's business but the result will always speak. Bitcoin is personal and what you need to focus on is how to accumulate your bitcoin and make a better profit as result and nobody cares about your own result. Their is no need to be worried about others people investment.
We cannot have such opinion when we engage in public discussion such as this topic. One of the benefits of discussion like this is to support others and encourage them to buy Bitcoin and hold as a way of taking their financial future seriously. I know you can only make suggestion and it is up to individuals to use the information or now but it will be very fulfilling to know that your advice and suggestions are able to make someone start buying Bitcoin to HODL, such action will definitely be remembered by the investor as a wise counsel. Let us continue to support and encourage people to buy Bitcoin and hold for the future.
