Unfortunately a lot of people are currently in the ruin because they bought at an ATH. It's rather sad. So no system is perfect, because people who don't know much other than it's a good opportunity could end up losing big. It's the luck of the timing.
It is not about luck it is about knowledge and common sense, if I had discovered bitcoin just a few months ago, I would have taken the time to look at its previous history and I would have realized the price was at its highest point and I would not have invested until the price dropped.That is the habit that newbies and other cryptocurrency investors should avoid, investing in a coin where its price is at all-time high. They need to educate themselves first on how and when to buy a coin properly. Researching a coin's price history before buying it will give you the right decision to invest or not in that particular coin.
