Cryptocurrency lending is a good offer, but it is not yet widespread due to several drawbacks: high volatility of the cryptocurrencies; too little acceptance worldwide (not everywhere accepting the cryptocurrency for payment);
but with the big spread of cryptocurrency, it will really be very good, because the banking sector is now strangling people with its loans!
Even if all these issues get sorted out, it won't make Bitcoin loans more feasible
Lending money assumes you provide collateral for the loan, i.e. you enter an agreement with the lender (for example, a bank). So if you fail to return the loan, you may legitimately lose this collateral, which means its forfeiture should be enforced somehow (read, your property can be taken by force from you without your consent). But how are you going to do this stuff with cryptocurrencies unless there is some legal entity lending you coins officially, which means full legal recognition of cryptocurrencies? We are far from that
