what would you check for, if you were to trade a token on premarket today ?
There is no need to observe a lot of premarket token trading. Usually, it is possible to earn a profit by trading a few things. First, the roadmap has to notice and see what their next step is and what they want to do in the future. Secondly, the total supply should be viewed and how many holders are there. Then it would be very easy to choose what the price might look like after Premarket Token. However, before a token is listed, I do not trade any kind because it is often lost. That's why I avoid the coins of the premarket.
There are lot of projects today that doesn't follow what is on their roadmap because plans may changes as many projects do fails. To me what that is mostly important in premarket (I can assumed you are talking of about their pre-sale) is that you must look after the team their years of experience and how well have they been Good in other crypto related projects, as most of them claims what they aren't so it's good to make further findings especially knowing their co-partners and investors is also very good. Again, you can also look at the circulating supply, Total supply, teams allocation and as well as allocation for marketing, including their usecase and prospects. All these constitutes to knowing how a project could becomes successful.
