They will panic and make decisions without thinking twice. They cannot find more information about the situation that is happening so that they make instant decisions. For those who can still be patient, they can see when they can sell their Bitcoin and take the profit.
Sure.. so what.. there are people who overinvest, and they don't know how to treat bitcoin like a long term investment rather than worrying about playing the price waves. Those are temptations that each of us have to overcome in terms of putting practices into place in which we make sure that we have long term accumulation plans that don't necessarily involve selling until after we might have already created a decently sized BTC stash.
Yeah of course you are right because one of the factors that courses such panicking is over investment which could sometimes caused by fear of losing out buying opportunities because this factor has propelled numerous investors especially the new ones who doesn't have a good knowledge of investment to get into trouble on the long run, actually being consistent on accumulating Bitcoin is very important but with the length at which most investors are going about it is actually wrong because whenever they see a buying opportunity they tend to invest everything they have at that moment and later they will start having some difficulties taking care of themselves and from their all they will be doing is monitoring the price of Bitcoin and of course it will surely result to a serious panicking which can even results that investor selling his investment.
So actually most of the failure of investment is caused by greed and poor planning because an investor who has a clear vision of holding will never be clouded by greed of taking advantage of any opportunity because his target is for a long term holding and to remain sustainable their most be some measures and limits so that his investment will never be affected on the process.
