Early 2016...

[BOOM]
@leprechaun: Hello, Mr. Larimer!
@dan: How did you get past security? And who are you?
leprechaun: Hello I'm leprechaun. It was pretty easy. I just set my machine up after you later moved out.
dan: Talk sensibly!
leprechaun: No hard feelings, sir. I didn't understand you much when you used terms on Let's Talk Bitcoin like 'velocity' and 'position' and you're not talking about physics but economics. I apologize for just showing up like this in your office.
dan: Well, you seem harmless. What are you here to say?

[ Cliff enters the room ]

leprechaun: In a few short months, you and a Ned something or other fellow are going to invent the Rain protocol and Rain token. Please do not include memos in your payment protocol.

dan: Don't worry Cliff, he looks like I could lick him in an arm wrestle. This is my security guard, Cliff. Cliff meet leprechaun. Now leprechaun, why would memos be a bad thing?
leprechaun: Well exchanges that accept Rain in the future will demand its users to enter specific but seemingly random strings into the memos, so you'll have to copy and paste twice and there will be many errors and lost funds. Errors will mean people will lose their Rain.
dan: Hmm... anybody smart enough to run an exchange would be smart enough to understand that they can simply send to name and there is no need for memos. If your user name sends the funds, they immediately know it's from you. There will never be a need to generate new addresses for each customer like with Bitcoin. Please escort this short man to the door Cliff.

[leprechaun and cliff leave the office]
leprechaun: Do you think I convinced him?
cliff: I'm not sure, he sometimes thinks a long time before coming up with his new ideas. How do you think you can know what he is going to do? Are you a time traveller?
leprechaun: Big muscles and big brains are not mutually exclusive.
cliff: That's true but how do you plan to get Back to the Future? if the time machine didn't come here with you.
leprechaun: I'll take the long way the same way I got to 2025 before. Tell you what, next time, in October 5th, 2025, I'll send you back as well. Just meet me in the office where I appeared.
cliff: Why don't you go to 2010 and mine bitcoins?
leprechaun: Where would I go? How am I going to setup? I have a double of myself living and is being tracked by the FBI and what not in my old place and the fiat money I could get is too new to be useful here and the Bitcoin I will had doesn't yet exist. How would I get even access to plug in my machine to power and ethernet?

[ Back in the Office ]
@ned: Another kook got in again?
dan: You'd better get rid of Cliff. He seems to be leaking our conversations. It's hard to know who to trust.
ned: Yes, clearly. Let's change the names. We'll call Rain Steem and call Thunder Steem thunder!
dan: That's not such a bad idea. Like a play on esteem. I'm not sure about Steem thunder, though.
ned: Why wouldn't a time traveller go back to 2010 to mine bitcoin?
dan: Yeah right. Any time traveller would be a Bitcoin whale.
ned: Hmm... do you have a Delorean stashed away?
