Stumped

I asked my girlfriend to ask me anything about bitcoin that she wanted to understand better and what she asked stumped me. She asked, if a small child wanted to open a lemonade stand and sell cups of lemonade, but was not allowed to use any technology (could basically only accept cash), how could they get paid bitcoin. Assuming they can’t create a wallet, etc.

Similarly, if there was no power at all in a city for days (like after a hurricane) and people didn’t have their phones or access to the internet, how difficult would it be to use bitcoin? Isn’t cash much easier?

I couldn’t think of any good answers to her questions. Any help?

Not ready to go public? That’s the perfect time to think about going public

The disastrous failure of WeWork’s non-IPO provided not just a dramatic crash-and-burn spectacle, but also a valuable cautionary tale about how not to do an IPO.  Even if your company is not ready to go public at the moment, if there may be an IPO in your future, things go more smoothly for companies that begin the work well in advance.  As a financial manager who consults for public and soon-to-be-public companies, I’ve worked with organizations traveling along a well-planned path, and those with an IPO date looming and management panicking. Here’s what I’ve learned in the process.  Have a business plan that demonstrates a path to profitability The first tech boom clearly demonstrated the folly of having an IPO with nothing more than “a good idea.”  Now, especially after several high-profile IPO failures, investor sentiment has swung to favor companies that demonstrate a solid growth history and a clear path to profitability. Go disciplined or go home Ven...

Oh no!!! The price of BTC is dropping because of this and that. Who cares? I sure don't, because I am betting on the potential of Bitcoin as a medium of exhange in the long term.

I love how people don't get that many are super long on Bitcoin because they understand it will be how money is commonly exchanged in the future. It's not just speculative. There is no central authority and no one single company pushing it, so yes, so the development of payment networks, apps, infrastructure, and so forth is taking a while. Look at innovations like SegWit and the Lightning Network. These are only the beginning. The improvement of renewable energy should help with mining as well. As Mark Cuban put it, Bitcoin will reach the masses when it's so easy your gma could use it. Well, it's taking time, but the technology that will be behind bringing Bitcoin to the masses will be no more complicated than the technology behind paying with a debit card at the grocery store. You just don't think about it because they have boiled a system that reads a chip and then instantly transfers funds from your institution to another across hundreds or thousands of miles d...
