For how much can the token's price increase over the year?
It is impossible unless the developer comes back. Perhaps all price increases are pump and dump.
Also, since Picoin has its own block chain, I think it is not a token but a coin.
Picoin has its own blocj chain yet? i have 50K Picoin on novaexchange buy at 150sat , looks like it never pump back to 150sat now. Any other exchange will list Picoin ?
Yes, Picoin is not a token belonging to Ethereum. It is a coin that adopted the X13 algorithm.

Exchange is only NovaExchange.
Since NovaExchange closed in 2018 and announced plans to become a new management team, there is a possibility that Picoin's dealings can not be done at that time.
