Hi all.
Say I want to provide micro lendings, how exactly does it work with the fees?
In electrum I can choose how much fee I want to pay, but if I put it on low it will take a lot before it confirms, if it ever confirms.
When i put the default fees it can be like half of the borrowed amount.
Who pays the fees in general and how can it be worth it to take/give a micro loan if the fees are so high ?
Generally, you just don't do any loans under 0.0025 BTC since it's going to be not worth your time and effort. If you do though, then ask the person to include in their repayment transaction fees as well. Obviously you shouldn't have to cop this fee yourself.
If you're lending microloans out, then potentially you could look at using dogecoins which has a super cheap blockchain fee, and is widely recognized as a liquid altcoin, even though it may be not stable at times.
Alternatively, use offchain transfers via coinbase/xapo to send out the loan. Would not recommend taking these micro-loans in the first place, though.
