Are there any Bitcoin Loan services out there at are actually worth borrowing from?
loan are good ideas for me like in local currency you can loan money, but have a problem for you request about bitcoin loan because bitcoin are really can't control the movement sometimes goes falling dump, sometimes faster up, example you can loan of btc in lower price but you need to pay at the time btc are in higher rate price do you imagine what i mean.
You mean that he can borrow 1 btc and in that moment price can be 3.500$, if he spent that bitcoin and after, let's say a month, he need to return the loan and what if price rise to 5.000$? Now debt is 1.500$ higher and you need to give back much more then you loaned in first place, that's why its not good idea to ask for loan in bitcoins. But fast loans where you can earn more money in fast time are worth rmthe risk maybe, that decision is on people who loan money.
Except btcjam, lending section here, I think poloniex also have lending service, I didn't try any of this things, but I take a look on landing section to laugh sometimes how people wish to borrow bitcoins with new accounts and without any collateral.
