Regarding pre-IPO tokens - if it's an airdrop, you can grab it; if it's real money, it's better to just watch.

If it's a good target, it's likely to make money - will it still be our turn? Underwriting and pre-IPO transfers are a highly mature industry chain.
If it can flow into the crypto world, then it's the traditional group of people who are not wanted... Why not? It's definitely not because of poor liquidity... Maybe the price is off, or there are restrictions we don't know about (voting rights are definitely not included).
Currently, it seems that the prices offered by various parties are lower than market expectations; keep in mind that the shell shares of such SPVs also incur costs—compliance, taxes, capital costs, etc. There are a few possibilities for why they can offer to the crypto space:
1. They think there's risk, it's too high - seize the momentum and exit quickly now.
2. They bought too much before at a lower cost, and now they want to hedge a bit.
3. Exchanges subsidize and buy to distribute to users as benefits.
4. Converted into pre-IPO transfers, with the trigger conditions met.
5. Crypto funds are finally picking up?! Recognized by the capital market?
According to recent crypto market patterns, where capital is the last to arrive, if you can grab it, don't buy.
