One of the privilege earned by holding your native token is the ability of early bidding for new tokens, how many token does one need to be able to enjoy this privilege? And how does the other community or the projects' team will think about this? Most exchange will not disclose the date and list of new token listing, and this feature propose a "violation" to the unwritten rule.
It will be listed and then locked for trading unless you have the required amount of tokens, 100, but subject to change in favor of users based on market conditions.
Just to make it straight, the owner of 100 NEXT (subjected to change) will earn a privilege to buy and sell newly listed tokens up to 14 days prior to public listing? Or will it be listed and then locked from public?
Let's say, an ABC token is to be listed on January 15th, will the owner of 100 NEXT be able to start trade them from January 1st or will they still only be able to trade from 15th (whereas the other will be able to trade on 29th)?
You have it correct in the last part. Once it is listed on the 15th, holders will have access on the 15th while everyone else will gain it on the 29th.
