how can you know how many tokens are sold? where did you see it?
It's very easy to check. The q1s tokens are so-called ERC20 tokens, i.e. simple Ethereum tokens that are used by basically every ICO in existence.
ERC20 tokens, like all Ethereum contracts, are public as they are stored in the blockchain. One way to check this public information is to use a site like etherscan:
https://etherscan.io/token/0xbeebcfe2fbb3c72884341be2b73ae0fc6559b8fc#balancesIn the above link, I show the token holders of the q1s contract. On rank 1 you see that 99.2756% of all tokens are held by a single holder, i.e. quantum1net. This means that only 0.7% of the tokens have been sold.
If you click the "token transfers" tab on etherscan you can see who has bought q1s tokens, when they bought, and how much they have. We're down to about 1-2 transactions
per day now, and there is almost zero volume of tokens being sold. In the past 24 hours, less than 250 q1s tokens were sold which is about €750.
All of this information is public and you can verify it yourself, don't take my word for it.
Also note that the q1n team has gone completely silent. They no longer post updates in this bitcointalk thread, questions on reddit go unanswered, their twitter account is just posting links that have nothing to do with q1n. Why are they silent? Why won't they answer questions? I know the answer, but you'll have to think about that yourself.
