Parking $100 to make $3.5 sounds convoluted. Even at $10000 what you’re gonna risk that for $350? How about I just park my money in a cold wallet and focus on making more sats. 

 So you really don't have any money in a checking or savings account denominated in dollars? 

 I have enough to make fiat based expenses in for the for seeable future but it’s not there to make a yield.
