I am very sure about it, that people actually knows the danger attached to investing in alt and shit coin, but they mostly let greed for bigger profit becloud their sense of reasoning, you will hear something like this from a motivational speaker that if you can invest in a coin that the price is 0.00000002, if the price gets to 1 dollar, you are f**king rich, which is very much unlikely, and once the price of that coin collapse just as this, forget it, your investment is gone.

 But with Bitcoin, even though their may be a sudden collapse in price just as this, it will always recover, because it has proven itself over and over again since it existence that it can rally back, so to me, what is very important is continuity, and Bitcoin gives me that,  so their is no point getting greedy and risking my hard earned money on any shit coin.
