Unfortunately, I think that the lockdown isn't a signal for aggressive spreading bitcoin. Your example is obviously not actual because that man has no money at all, he cannot pay for his bills, how can he be BTC investor now? Okay, let's imagine that he sent his money to buy cryptocurrencies; there is a huge risk he'd soon need to take that money back. Thus, he'd cause volatility which is good for market in its speculative meaning, actually. But I wouldn't say that helps bitcoins a lot.
