You can just use the pool to swap hive for PLN
or place a buy order at current value of ~1 and give it some time.
If the buy order is slightly above pool value, a bot might even go fetch it for you (this applies to any token with hive paired pool, as far as I'm aware) since they automate this to gain some small % from the difference in trading value. So, that being said, it still implies to bypass the automated middleman is optimal, and swap hive directly into the pool (or be very patient with buy orders waiting on someone to crash into them)
The swap for PLN:HIVE can be found at this beeswap link:
