Sometimes it is not actually planned, one situation or the other can make you request for payment even for a much more lower amount.I feel if we are taking crypto payments then it's ok because the fee is not too much when we get paid through crypto but if we opt this for Paypal then we are paying a very high fee to Paypal and this is the reason you won't see me going for lower payments and I like to get at $30 minimum on websites that I trust.
Why do You Request Payment at low amounts?
