"SALT Lending launched in early 2018, allowing cryptocurrency owners to take out a loan using their crypto as collateral"<p>I guess the math for such a business is:<p>- User deposits crypto worth X dollars.<p>- User can take out up to X * Y dollars as a loan.<p>- If the value of the crypto falls below X * Y * Z, it gets liquidated<p>Where Y<1 and Z>1.<p>Any ideas, what Y and Z usually are?<p>I also wonder what the use case for using such a service is? Anybody here ever used such a service? If so, why?<p>My vague feeling is that it is for tax prevention? Say you bought BTC for $1, and now it is worth $101. If you convert it into dollars, you will have to pay taxes on the $100 you earned. If instead you loan $90 and hand over your BTC as collateral, you do not have to pay any taxes, correct?
