Honestly, I really don't get what your question is. Kindly correct me if I am wrong, you were asking if there are cryptocurrencies that will just bring loss if we invested to it? If that is the case, you can easily find shit coins by just reviewing and scanning their whitepaper and website. By also just joining in their telegram, you will see if the team is active in answering possible investors concern. If they are inactive most of the item and just want you guys to receive their money, you need to avoid that coin, 90% that the coin is a scam.
