Investing is work. You have to spend time researching different opportunities, and even then there is still a risk involved.
If you made money by buying bitcoin a long time ago, you didn't get something for nothing. And if you sell it now, you can profit before the game of musical chairs collapses. So there is a limited window of arbitrage.
A little bit of work multiplied by a lot of risk and time.
