Here’s what I started with a little over a month ago. I put in ~$500 AUD for 0.0572btc. Bitcoin was around $8000 AUD at the time. The 0.0139 is the 24% payout i’ve received since then and is currently worth $310 AUD with BTC sitting at $22600 AUD. This payout will continue until it reaches around 140% and the lending contract expires. It’s recommended to take out your initial investment as soon as you can (about 3 months) and then keep lending out the money that’s leftover and grow it from there for free essentially.
This isn’t a concern, however, because the bitcoin network runs on consensus, and accepts whichever blockchain is the longest. In practice, this means that whichever blockchain has the most computing power behind it is effectively guaranteed to win, as they’ll be able to calculate the solutions to the hash problems and find new blocks faster than their less powerful competitors.
