yes there is no doubt about this that loans are too risky so you should be careful when taking loan as there is always a chance of loosing bitcoins if he price fell down so try not to buy or do trading on loans as you will then not be able to return it back.
what is the risk in taking a loan

the risk lies for the individual giving out the loan ,doing trade and gambling with loaned amount is a very risky thing as you never know when you are going to loose everything,bitcoin and price really never matter if you are not looking for a profit every month.
Maybe he is afraid that he might be tempted that he will not be able to repay his loan due to lack of control in the lending operation, even if you get a loan easily but you cannot consider it as a free as that is a sin not to repay loans and just take the money of others illegally.
