If bitcoin goes to $120k and I sell 2 whole bitcoins ($240k), how much tax will the government charge me if I live in Florida and only earn $50k a year?
Actually op, it's quite funny that the title of this thread is totally different from what was written down and besides you would have thrown more light on what you were trying to say, so that you can get your desired response and suggestions you might be looking for.
And talking about the title of the thread, it's actually not a bad idea, because real estate is one of those lucrative Business or investment that can stand shoulder to shoulder with any business or investment in this whole wide world, because it's also an asset that appreciate in value overtime, just as Bitcoin is.
And as for the tax that will you will have to pay in Florida, to be frank with you, am not a citizen there, I wouldn't be in the best position to answer that, I believe that your fellow Americans will be in the best position to answer that.
