Heads up, awardtrail readers! There's a potentially lucrative opportunity to snag some bonus cash by signing up for Kraken, a cryptocurrency platform. Through shopping portals like Rakuten and Topcashback, plus a referral bonus, you could pocket a nice chunk of change for trading crypto.

Here's the deal: You can earn bonuses for signing up via Rakuten (12,500 points/$125) or Topcashback ($202!), PLUS use a referral code to earn even more based on how much you trade (up to $150). The sweet spot seems to be trading around $500 worth of crypto. The article details a strategy to buy around $260 and immediately sell for ~$255 to trigger a good chunk of the referral bonus. You can also grab a free trial of Kraken+ to avoid trading fees for 30 days – just remember to cancel it!

Now, a word of caution: Trading cryptocurrency involves risk. Even with free trades, you might lose a few bucks due to market fluctuations. The article author even mentions losing $6 on a small Bitcoin trade. So, do your research, understand the risks, and only trade what you're comfortable potentially losing. Also, the referral program isn't available in every state (sorry Maine, Washington, and New York!). But if you're comfortable with crypto and want a relatively easy way to boost your points balance or cash, this could be a worthwhile opportunity. Make sure to trade within 30 days of signing up to get the bonus!
