Of all the large companies that are now large internet players, do anyone particularly scare you in terms of how you data and track could be used? Amazon, Facebook, Twitter,
?
I'm not scared of any site that could possibly trace my transaction history, what's I'm afraid of are the hackers that can steal my bitcoin from my wallet. Time will come that Amazon, Facebook and other big name in internet market will adopt cryptos just like a normal currency, they will somehow require KYC for every transaction but I don't mind that as long as they will not do bad on my bitcoin and earnings.
Well these companies are also bound by laws and they know that there will be repercussions once they violate their cust's privacy and trust. Big companies put premium in securing their customers' information so i'm not really concerned. Their reputation depends on it anyways
