when u take out a loan against bitcoin, u are essentially signing up for enforcement of the fiat system against urself, in addition to many other enforcements u already signed up for in ur fiat life; if u think it thru, fiat money does not work without the enforcement units, and those are controlled by the fiat religion & fiat money;

bitcoin does not have any violent enforcers, the only enforcement are the rules of the code, so it is inherently much safer than playing around with fiat tools on bitcoin;
