Bitcoin is a good way of promoting your business.there are no delay during payments, onlike are local banks that go on Holidays, Bitcoin doesn't go on holidays. The are available 24/7. Let's all make good use of Bitcoin in our business. Bitcoin transactions can cost just fractions of a cent and it's really good for international payments.
Banks in your country don’t work on holidays? Also it is inaccurate that fees are always cheap, it’s not unusual to see high fees when the network gets congested. If these are your only reasons why businesses should adopt bitcoin then you probably won’t be able to convince anyone.
I do think that the support would be advertised as 24/7, however, the hours during the holidays would be smaller.
And, yeah, fees may be big sometimes - it's inevitable with the current state of things.
