Per CMC, the total tokens now is only 236,881 SUR.
That's very small, price should be at least $1 now, what are the reasons why it dump? maybe because of the lack of liquidity?
Trading volumes are small. Nobody needs SUR. That is why the price of the token is so small.
When cryptocurrency market falls so active it is very difficult to do something for the development of the tokens. It is necessary to wait the full recovery of the market.
