Three things not to do with long-term altcoins:

Don't choose altcoins with too large market capitalization: altcoins with too large market capitalization tend to have experienced a round of prosperity and are at risk of being replaced. For example, EOS, BCH, BSV, IT C, TRX, XRP, FIL, LUNA, and the current ADA, DOT, LINK. These currencies may be replaced in the next round of competition.

Don't choose altcoins with too low market capitalization and almost no trading platform: Although the last round of Dogcoin has all the achievements, except for SHIB, most other altcoins are just cutting leeks. Therefore, don't bet on altcoins with too low market capitalization and limited trading platforms, because the probability of success is very low.

Don't choose altcoins with old concepts and lack of novelty: This market always tends to speculate on new rather than old, so when choosing altcoins, try to avoid choosing those with old concepts and lack of novelty. A better choice is to choose altcoins with fresh concepts, because it is more likely to attract market interest and attention. Simply put, choose those fresh and creative altcoins.
