One of my colleagues is from north Africa and worked in Europe to send money to his family and friends, investing in BTC as it was easier to handle the international transfers. This was a great use for BTC in my opinion and it helped him raise his close ones out of poverty on paper :)
But with the dip, and people believing in the staying power of BTC, a lot of those funds are compromised now. They're not ruined and people are still better off than others, but there's a real concern on if it will be worth it to continue with BTC; the buy-in price is now higher than the current price by far and the total investment has devalued greatly and continuesto devalue without a lot of insight as to why or what can even be done.
So I think the personal stories like this emphasize the importance of the drop, especially since 20k was a fairly signofjcakt growth point for BTC as I remember it.
