My Personal Opinion on Altcoin Investment I'm writing this again after posting in October, but I still have no desire to buy altcoins. Currently, I'm only interested in Sky and Aave, which are consistently conducting buybacks and generating actual protocol profits. Today, I'd like to discuss the characteristics of altcoins to avoid. 1. Is this a chain that requires subsidies (incentives) to use? Newer chains like Monad and Plasma are currently distributing massive token subsidies to inflate their metrics. These coins should only be used for short-term transactions, and a strategy that works is to sell them after receiving the subsidies for free. There's no reason to buy them. On the other hand, protocols with robust revenue structures like Aave don't provide their own subsidies; instead, onboarding token foundations directly provide subsidies. If a chain relies solely on receiving funds to survive, the ecosystem will inevitably collapse when support is cut off. 2. Murderous Tokenomics (Circulation Plan) This can be easily verified through Upbit's "Circulation Plan" or Binance's "Token Unlock" information. Many coins typically release 5-10% of their circulating supply each month, but many of these coins have lost more than a tenth of their peak value. Among major coins, **SUI** has a relatively fast actual circulating supply. (This is because initial investor allocations, not staking rewards, are still being released.) 3. Excessive listing fees paid to alternative exchanges I didn't trade stablecoins this time, but I saw that exchanges like Phemex were also paying listing fees. So, instead of buying, I only took a small short position. If you see listing fees being paid to unfamiliar exchanges that no one around you uses, you should be suspicious. Stop losing money by buying altcoins.
