If [ bla bla bla ] you [ bla bla bla].
An if you were not scolding me for things that you say I would do if I had not avoided to do them, you would be killing baby seals with a railroad share to make leg warmers for your pet unicorn. What a shame.

I believe your mission is done here. Thanks.
You are welcome.
Pif I wanted to send you some brazilian reals for your valuable insight about how to improve this product, it would take at least a week for you to receive it and you would receive at most 95% of the value I sent you. Do you consider the existing payment system optimal? Can't you see some benefits in Bitcoin now?
If you were to send me some bitcoin, I may get 75% of what you spent to buy it a week ago, and it may get stolen by a hacker or a trojan in my computer, unless i get a second computer just to handle it; and if it gets stolen or sent to the wrong address, nothing can be done, it is lost. Can't you see why people are not rushing to use bitcoin now?
I wouldn't send you Bitcoin if you did not have a Trezor, to protect you from thiefs and hackers. Also, I was talking about a hypothetical situation when Bitcoin would be adopted worldwide. If that is the case, price would not be that volatile. But, that would never happen if there are no guys developing such a great product like Trezor. The wide adoption would not happen today or next week. The Bitcoin will see a couple of price drops before that happens, so your warnings for investors are quite accurate. The point is, you should not dismiss the technology and the BTC as a payment method, because it's not going away.
