The longer that i been in bitcoin, the more difficult it comes for me to imagine guys who have spent enough time accumulating bitcoin to put them in a state of over accumulation, and surely accumulating bitcoin through a whole cycle might help, and also front loading the investment might help (which presumes bringing capital from somewhere else beyond just normal pay/cashflow). So frequently I have been witnessing guys describing themselves as having had reached a status of overaccumulation much earlier than they had actually reached such status.
If you mean a lot of people are making things up or lying about their bitcoin portfolio. I think it is their right to carry out this lie. However, this will still make the person bored with his own lies. Because lying will definitely make someone have no trust from other people or from themselves. However, I am sure that not many members of this forum have such habits. Besides, talking about excessive investment, I don't think this is a bad thing, especially investing in bitcoin. Because as discussed in this thread, Bitcoin has the potential to continue to increase. So if you think about it logically, having more bitcoin would definitely be very good, because the profits that could be obtained would of course be very large. But everyone definitely has a different perspective regarding this, because if you think about it from the negative side, accumulating money in one point (assets) excessively has a risk that is not small. But we're talking bitcoin here, so that shouldn't be a problem.
For a certain person to lie or not in regarding about their portfolio then it will really be that up to them, you might be able to impress other people but what is actually the thing that you will be able to get or gain from it? You will be getting that amusement or praise or good words from other people but in the end of the day you will really be just that having that kind of emptiness since you do know on whats the truth on what are the things that you are really having or dont have. So there's no point on trying out to impress other people since you wont really be able to gain something from that but rather you are just that lying into yourself. So it will really be that important at least that you do have those kind of silent accumulation and do know on what you are doing.
Buying or Selling will really be basing up into someones knowledge and approach towards this market because on the moment or time that you will be having that kind of pretending that you do have that tons of coins but truly you dont even know on how this market behaves then you are just fooling yourself. One of the main reasons on why we are here on this market is that we are trying out to make money with it and its a normal approch. You should be that wise on how to make up such actions. Buy or DCA when you do see the market is dropping and selling it out when its peak but of course there are those people who will be deciding on holding it up.
