I heard someone's "operation" was exposed, so I'll just come clean.

Actually, many people are using this approach: exchanging margin for coins, staking mainstream cryptocurrencies, then swapping for U, and depositing U into a savings account to earn 20% returns—basically, just sitting back and collecting money. Since the news has gotten out, you definitely don't want to miss this opportunity.

But I must say upfront, investing involves risks, and returns will fluctuate with the market. This strategy is for reference only. Trying it out might just be gone.
