people have been complaining about it ever since they mandated BIP70 so there are posts on their blogs about it which you can read https://blog.bitpay.com/bitpay-and-payment-protocol/ it may not make complete sense though. and i have heard once before that someone said it is done in order to make it near impossible for those using TOR to be able to use Bitpay! don't know how true this is though!
interesting, thanks for that. i've never been able to figure out why mandating BIP70 would be a good move for them (unless it's true that people screw up the address/amount and so they want to avoid dealing with that).
people tend to spend their bitcoins when they have risen not when it is going to rise. it is the same as selling, you don't want to sell at the bottom, you sell on top.
what makes you think that's what most people do? on the contrary, i think most people sell the bottom and/or buy the top. they get greedy when price is rising and don't want to sell. that's why the old warren buffet saying always applies.
