Don't know, no fiat exchanges list Stratis, but you can wire transfer to buy bitcoin in bitfinex, and then withdraw and buy stratis in polo or trex.

Is there a link for details?

There is poloniex, bittrex, Bitylicious, and most recently Binance. Pick what is convenient for you and hold your stratis.

The technology used is known as progressive web app, feel free to have a look to the white paper, it describe it a bit : https://ico.selfpay.asia/pdf/whitepaper-selfpay.pdf

please dont waste your time trying to get listed on yobit, and def dont waste your money doing so either. if there are any updates for this coin, yobit will not update their chain and those coins will be held captive on their exchange. it would be better to try and get the word out about the coin for an exchange like cryptopia, but there isn't much to say about it yet until the dev's start releasing stuff after block 200,000. i think it's too early for an exchange at this point, if you are trying to sell your coins you might be better off posting an OTC add or thread on here.
