The Asian and European markets in the cryptocurrency world are both lacking in funds, and their market manipulators are very cunning, playing with you through fluctuations. If you use right-side trading techniques, they will make it very uncomfortable for you (for example, with aggressive points). If the points are not accurate or good, you won't make any money, and the technical requirements for short-term trading are very high. The advantage is that they don't have as much money to pump or dump, so it won't be very extreme.
The US market is like the personality of Americans; it either keeps rising or keeps falling, without giving you a chance to turn back. That's why you can see that as soon as the ETF opens, the fluctuations are very intense and the trend is basically designed to trick you once, such as first surging and then crashing hard at closing, or continuously dropping at the opening and then when you wake up, they pull it back up aggressively at closing. However, their style is straightforward and clean.
