Even if someone tells me today that bitcoin will get to $2m before the end of next year, I will believe it.
Even though we don't doubt that bitcoin will increase in due time, we should also be more realistic to know that bitcoin can not just grow to $2m dollar In the space of 1 year. That would be a massive push of %millions. even as though it was just a speculation but it may not possible anytime soon.
Over exaggeration has been a reason why investors are getting in balance (less or no profits) while investing, they invest too much of what they have in anticipation of making massive profits due to some rumored or questionable speculations that is likely not to happen and this tends to put them at risk.
Any investor who is over investing more than his means is not a wise investor, because everyone who invests in bitcoin, be it for the short term or long term understand that before investing in bitcoin, there are certain things that's to be observed and one of it is, not investing more than certain percentage of your disposable income. So if there are any investors out there that's over investing more than he is supposed to invest,because of speculations made by people as him is not a wise investor, but an opportunist who is greedy and deserves whatever he gets at the end of the day. Even if such person gets into trouble I don't care.
Because an investor should be wise enough to understand that speculations are just there to make people see the level at which other market players thinks bitcoin could be at that time frame. Those the people speculating never gave any guarantee that it would happen. So why would you go and over invest because of that, and blame it on others. If you are part of these sets of investors doing that, you have to refrain from such practice.
Perfectly said, this over investing is same or almost same thing as aggressive investment and just like you said, it has been advised not to invest aggressively because a situation where an investor has used up his or her reserve and emergency funds because of the quest to have more figure of Bitcoin in their holding can result to taking profit premature if at all there will be profit and any investor who does this automatically means he or she lacks management skill. Management skill is the ability of an investor not be drive or moved by the market Dip and mismanagement of investment in this context is a function of greed ( wanting to hold more than you are not suppose to...), though it's not bad to take advantage when there's Dip but it should be within your control and capacity.
