You're right, because of the low volume of SFU trade, you can no longer find it through a search on cmc, but the direct link works - https://coinmarketcap.com/currencies/saifu/. On cmc no charts from the exchange. In order for the chart to be reflected, the trading volume must be at least $100,000/day.
However, in connection with the Saifu campaign to buy tokens from registered customers, demand has increased and the price on the exchange is now 0.00001800 BTC ~ $0.1164 - https://www.idax.mn/#/exchange?pairname=SFU_BTC. I asked a question about the plans for the listings, and I was told that the next exchange should correspond to the European AML. And this is a success, because it will be a famous top exchange, I think.
Given that the company is growing and developing, it releases updates, it is already making a profit, I am calm for the price of tokens, I just have to wait a bit.
I remember the story of my friend, who mine BTC, when it cost $5 and sold. And now regrets. We all need patience. This is a very important quality for the trader and investor. Good luck!
We need to adopt realistic approach as this point we can't compare this BTC which has totally different structure. This is very disappointing situation for early investors we will get stress because of current situation and see very slow progress done.
