1) Lend Bitcoin to Others The concept of lending Bitcoin is relatively simple. You buy (or mine) this currency and then lend it to other people or businesses. There are websites that serve as a middle man between you as an investor and other parties that would like to get a loan in Bitcoin.  For instance, here are the 3 best Bitcoin lending sites, so that you can take a look at the process and available interest rates. However, we must warn you that lending Bitcoins is more dangerous than lending traditional currency. Since this market is not fully regulated, interest rates will be much higher than usual. At the same time, there is a small risk that you will lose your money without the opportunity to get them back.
