Thank you @chefcryptoshark Actually for us is working much easier. For our finances is actually cheaper to accept BTCs for example, because we always ended up exchaging the profits to other fiats like USD or EUR and its free of taxation . So far our crypto clientele is too small to worry about drops in the price, because always in the long run BTC is going up. If it was a big percentage and we will have to use it for the daily costs Im sure we will have to implement this variables you mention, but always trying to make it a fair and attractive price for cryptos too ;-)
Thanks for reading, I'd appreciate if you help us to spread the word. Cheers!
