But I can't use bitcoin buying a coffee now, because the fee is so high, if I keep 0.0001 fee like before, it would take days for the transaction to get confirmed, I've got a transaction which took 11 days to get the 1st confirmation last month.
It's not cost-effective any more to buy (I mean both online and buying face to face) thing via bitcoin. And this is why I quit buy coffee with bitcoin.
It does not make sense to pay with bitcoin for orders that are shorter than 30 minutes. Because the payment will be confirmed within 10 minutes at the earliest.
It is currently not possible to pay with bitcoin for fast-food consumption like coffee.
And worst, transaction fee is way more expensive than a coffee order here in our country. It would be funny if you spend more on the transaction than on the goods that you bought. Only and insane person can accept that. But I think we just need to wait, developer is aware of all of this thing, and am sure there will be a fix for this, the only problem is when. But rest assured, we can enjoy buying coffee again with bitcoin in the future.
