just a hope? don't use it as a foundation for you to buy coins when you go down. use your analysis that will help you to find the best assets for investment. now all coin prices are down and cheap. Will you buy it all? of course not, choose the best.
Anyway, whatever you choose this will be the hope of future success. There are no guarantees here, so hope will somehow be present.
Even choosing technological projects that develop you will not be protected from failure. A good example of this is a cool project that works for godliness, trying to save from a number of diseases, but somehow the price is very small for it. Although the project really deserves respect and attention to viewing, by the way, this project is FOLDINGCOIN.
Projects have a real use, good purpose, technology and prospects, but unfortunately the price is very low. And what you mean is just hype coins, which are just bubbles, and have no real value.
