today i saw the nex token split allocation and was surprised to see a very low allocations for ESOP and company funds. Is it a bad idea to acquire more tokens from the free market, the current price seems to be near ico price 
yes, i thought traditionally, the company owns a little more than 50% of the tokens. For nash its around 25% including founders tokens assuming all the tokens reserved for partnership is spent. you are right, additionally around 3 million token is with the company thats left over from the sale.
