LOL, what should I do to proof it to you? Show the business registration certificate? Show you photos, videos of mining center? Will you believe? Of course no, so please stop acting like an over smart.
Trial plan is just a bonus for "people who are going to buy hashrate". That's why they can't withdraw mining reward from trial plan until they don't buy hashrate. It's not just an "airdrop" to attract people.
Airdrop program is another topic. It's related to Hashshare Masternode, not a strategic move for blah blah...

LOL contact us here and now... you didn't even check the website. Cool, so address in Kazakhstan is on the website, as it is headquarter. I will be happy to share other branch locations which you want (I know that you "won't" and "you don't want") to visit if you contact us by cs center, email and others.

PS: How to deal with the people who act oversmart
Ignore them. (As much as you can)
Node your head to 'yes' for whatever they say.
Remember that they are always right. (Even if they are not)
Don't ever try to correct them. (Unless you have so much time and brain to waste) (Also, because they are always right)
Often act as if you knew nothing before they told you. (Okay, so was it like that? THANKS for telling.)
