Please keep in mind the three rules for choosing altcoins:
Avoid altcoins with too large market capitalization: altcoins with too large market capitalization, such as EOS, BCH, XRP, etc., may have passed their prosperity period and face the risk of being replaced.
Avoid altcoins with too low market capitalization and limited trading platforms: altcoins with low market capitalization and limited trading platforms are often the target of speculators, with a low probability of success, and should be avoided from investment.
Avoid altcoins with old-fashioned concepts and lack of innovation: The crypto market prefers fresh and innovative projects, and altcoins with new concepts should be selected because these projects are more likely to attract market attention.
