Let's say I am the type of person who needs a cheap loan, and I decide to use Coinbase. My understanding is that money into Coinbase and money out of Coinbase is going to cost me 1.49% (at least) in each direction, and that's before the additional $1-$10 gas fees in each direction. So 3% + currency risks + whatever other fees + the risk of fat-fingering my crypto and losing it to the ether forever, and also trying to figure out if I have some kind of tax liability, BEFORE the actual interest rate itself.

Or I choose a well-regulated provider to do a money-transfer[0] to and pay a one-off fee of 3-4% for several thousand pounds for a year or longer loan, even if my credit isn't perfect, and I do that with the full protection of the legal system, including bankruptcy protection, easy resolution if I type the wrong account number in, etc. Those are the rates for if I need cash too, if the thing I need to pay for can be paid for by credit-card, the rate falls to closer to 2%...
