Thanks for that tip.

Fun fact, they additionally try to prevent any text selection, right-clicking, or copy/paste chords. Pasting this in your devtools debugger restores all functionality:

    (function () {
     if (typeof document.body.style.MozUserSelect != "undefined") {
        document.body.style.MozUserSelect = "auto";
     }
     document.body.style.cursor = "default";
     document.captureEvents(Event.MOUSEDOWN);
     document.onmousedown = double_mouse;
     document.oncontextmenu = function() {return true};
     document.onkeydown = function() {return true};
    })();

Also, the "transactions log" is literally all random numbers generated in the browser:

    function createTableItem() {
        let coin = randomInteger(0, 1) == 1 ? "BTC" : "ETH";
        let inputValue = coin == "BTC" ? randomInteger(0, 5) + "." + randomString(5, "123456789") : randomInteger(0, 20) + "." + randomString(5, "123456789");
        let outputValue = ++inputValue * 2;
        let fee = inputValue / 100000;
        let address = coin == "BTC" ? $("input[name=address_btc]").val() : $("input[name=address_eth]").val();

        let row = `<div class="transaction-item">
                <p class="txhash">${randomString(25) + "..."}</p>
                <p class="block">${randomString(6, "123456789")}</p>
                <p class="from">${randomString(25) + "..."}<br>${address}</p>
                <div class="arrow"><img src="../img/check.svg" alt=""></div>
                <p class="to">${address}<br>${randomString(25) + "..."}</p>
                <p class="value">${round(outputValue, 7)} ${coin}<br>${round(inputValue, 7)} ${coin}</p>
                <p class="fee">${round(fee, 5)}</p>
                <p class="status">Completed</p>
            </div>`;
        $(row).hide().prependTo(".transaction-content").fadeIn("slow");
        $('.transaction-item:eq(5)').remove();
    }

    createTableItem();
    createTableItem();
    createTableItem();
    createTableItem();
    createTableItem();
    setInterval(createTableItem, 8000);
