Never, There is none. Cryptocurrency investment or business is high risky business that needs patience, calculation and focus. It's not something that you put money into and make your gains immediately. Besides, no business start seeing it profit really fast, one needs to be endurance and before they can make it in this investment and of course making use of the money you are ready to forgo.
This market does in fact offers opportunities to make money fast if you enter in the market at the right time and have the right skills and knowledge to take advantage of it, but that is not easy at all and you are a little bit dependent on your luck, for example, last year the market grew in an incredible way so someone investing at the beginning of the previous year and selling at the end made a fortune but in order to have such a perfect timing you will need to be a very good trader and that can only be gotten through experience.
There is no "money here in cryptocurrency" if you look at it that way, you should look at crptocurrency as something new that would save us from the issues and problems from government backed fiat.
All these new coins are trying to achieve either of 2 things, either they are trying to make a better coin that all known coins or they are trying to make a quick buck on this gold rush. But don't forget, it wasn't the miners that money on gold rush, no it was the pickaxe sellers that made the most money.
