The quote is not from Satoshi Nakamoto, the creator of Bitcoin. The phrase "in case it catches on" suggests that the speaker is referring to something that has the potential to become popular or widely accepted.

A possible interpretation of this quote is that the speaker is talking about getting some Bitcoin in case it becomes a mainstream form of currency. At the time Nakamoto created Bitcoin, it was still an experimental and relatively unknown concept, but he wanted to make sure that his creation had a good chance of catching on and becoming widely accepted.

However, without more context, it's difficult to say for certain what Nakamoto meant by this quote.
