Random choice - betting script

I'm trying to make a betting script with random choices using Math.random, but it only chooses the same bet and it is betting a single time before it crashes.

Not sure what is wrong with the script.

var minstake   = 0.00000001;  // valor base
var autorounds = 99999;         // n° de rolls
var handbrake  = 0.0001;  // valor lose pause game
var autoruns   = 1;

function getRandomNumber() {return Math.floor(Math.random() * 2) + 1;
   };

function playnow() {
     if (autoruns > autorounds ) { console.log('Limit reached'); return; }

     if (getRandomNumber!==1) {
            document.getElementById('double_your_btc_bet_lo_button').click();
            setTimeout(checkresultslo, 123);
            return;
            function checkresultslo() {
            if (document.getElementById('double_your_btc_bet_lo_button').disabled === true) {
            setTimeout(checkresultslo, 246);
            return;}}}
     if (getRandomNumber!==2) {
            document.getElementById('double_your_btc_bet_hi_button').click();
            setTimeout(checkresultshi, 123);
            return;
            function checkresultshi() {
            if (document.getElementById('double_your_btc_bet_hi_button').disabled === true) {
            setTimeout(checkresultshi, 246);
            return;}}}
       }
     var stake = document.getElementById('double_your_btc_stake').value * 1;
     var won = document.getElementById('double_your_btc_bet_win').innerHTML;
     if (won.match(/(\d+\.\d+)/) !== null) { won = won.match(/(\d+\.\d+)/)[0]; } else { won = false; }
     var lost = document.getElementById('double_your_btc_bet_lose').innerHTML;
     if (lost.match(/(\d+\.\d+)/) !== null) { lost = lost.match(/(\d+\.\d+)/)[0]; } else { lost = false; }
     if (won && !lost) { stake = minstake; console.log('Bet #' + autoruns + '/' + autorounds + ': Won  ' + won + ' Stake: ' + stake.toFixed(8)); }
     if (lost && !won) { stake = lost * 2.1; console.log('Bet #' + autoruns + '/' + autorounds + ': Lost ' + lost + ' Stake: ' + stake.toFixed(8)); }
     if (!won && !lost) { console.log('Something went wrong');}
     document.getElementById('double_your_btc_stake').value = stake.toFixed(8);
     autoruns++;
     if (stake >= handbrake) {
            document.getElementById('handbrakealert').play();
            console.log('Handbrake triggered! Execute playnow() to override');
     }
     setTimeout(playnow, 111);
     playnow()
