That post has been writen so many years ago but it is in some way still true, cause eth price and other coins is going down but in few next weeks it will be x time bigger and investing now is a real occasion for investors...
Yes its true, this has been an issue always. But we also have to accept the fact that this business runs like this, sometimes it rises and sometimes it decreases. Its more like on looking on its value when to buy and when to sell bitcoins. Its always good to buy in a low price and sell at high price, i think investors already knew about it. As of today, its really a perfect time to buy for its price is low and i think more people can afford its price today. One thing i am positive about is that, before this year ends bitcoin will reach its highest price ever.
If your looking of a right time to buy i think now is the right time while the market price of ethereum is still very low because this is what investors are looking for is when the market value is decreasing.
