This is not financial advice. Listing may be delayed or may not happen, and ANT may trade below its offer price from the first day.
I don't think the market is the same as it was before, when new projects created hype and early investors made huge profits.
I'd say investing too early is advantageous, but the risk is too high as well...
For me, I'd rather wait to launch for proper observation. Besides, the real investment advantage is not for the one who comes first but for those who invest at the right time. It is better to be more cautious than to regret.
Early investment risk
overvaluation - the company sets a more promising price than the market value
market hype - buying price is higher than the actual price
market volatility - price decline is possible after listing
