Do you think the richest families or personalities in the world would be interested in using bitcoins??
Yes, and why not?, Bitcoin is not taxable, and no banks can disallow you to receive and send big amount of money in one transaction. Bitcoin is decentralized and so you are sure about the security of your coin, except of course if you are using exchanges which I only recommend when, well, exchanging.
And if so, would that be a good thing for us small people or negative??
I mean rich people are capabale of so much things, so it makes me wonder..
We all know that even a poor person who have enough skills, can earn and have their Bitcoin here, and having millionaire investors in bitcoin community is not bad at all, in fact, it can help pump bitcoin more if possible.
