Entrepreneurs can find for themselves many positive aspects such as: crypto-loans will attract new customers; the commission for transactions will be reduced; business will be perceived as a supporter of innovation; there will be new loyalty programs for customers.
I don't know about loaning crypto because it might be a little bit of a risk. Supposed that the day the loan was issued, the price of bitcoin was $6000 and (for simpler examples) the loan amount was 1
BTC, the collateral will be worth $6000. Loans can be long term such as months. What if after a couple of months, the price of bitcoin has skyrocketed and the person then decided that he's just going to let the lender get the collateral and not pay back. Pretty much the lender could have made way more if he just kept on holding his coins. The price of bitcoin has skyrocketed, but the collateral's price did not. What then? He just lost x amount of potential profit just by holding bitcoins. It's not like all loans are getting paid back and it's not like we can make the person sign a contract that they have to give more collateral when the price of bitcoin increases by the time the loan expires.
What might happen is that the collateral will be a lot more than the loan so the lender will have protection from such bitcoin-suddenly-skyrocketing dilemma. Which then discourages people to do crypto-loans as they will be safer just getting a loan from the banks where the currency's value isn't that volatile (although continuously inflating).
Also, why should there be new loyalty programs from the customers who are paying with crypto? What's so special with accumulating cryptocurrencies from such transaction that you're going to give them their very own loyalty program?
I think it is important for entrepreneurs to be one step ahead of their competitors. Therefore, if they implement the process of accepting cryptocurrencies for their goods, they will be able to attract a completely different market and this will be a plus for them. As for me, for me bitcoin is a speculation on which you can earn.
And that "completely different market" consists of how many people?
The amount of people that the entrepreneur will attract by accepting cryptocurrencies is so little that it's not worth updating their payment system just for that.
