The problem of Suretly is there is no demand in the tokens and tokens are not use on the Suretly platform. It is very important to create demand in the tokens.
That's the challenge the team are facing now, it's been 3 years (more or less) that's that I haven't seen its volume increase at a decent rate.
Now it's volume is only over $1K, but actually I'm quite surprise as they have added a new exchange as I check now.
They have Fatbtc on the list already, and it has the biggest volume of the two exchanges listed for SUR tokens, this is a small improvement but hopefully we will gain better volume as per record,
https://coinmarketcap.com/exchanges/fatbtc/ has over $1 billion 24 hours trading volume.
