This is correct. End of March there will be another round of the presale at Unicrypt, which will directly lead to a locked Uniswap pool.
Only after the Uniswap pool ist created the exchanges may start their trading pairs.
Exmarktes and Latoken will certainly be the first. We have severeal listing offers from other exchanges already as well, but it is too early to tell more at the moment.
If possible, don't chase these exchanges. 2 are more than enough to start with.
It is better to focus in your developments, and attract potential customers on your platform.
Because without them, the value of your token, even if it has very low supply, will not grow if your platform itself is not up and working.
I hope, I will not see a forever beta stage of a defi platform here. Make your platform an active one by attracting as many customers as you can.
