Aside of that, there were some false reports about Greeks rushing to buy bitcoin too, I don't know what level of fact checking those articles went though but since I'm Greek I know for a fact that this wasn't and still isn't true. It's true that the interest on it rose during the recent events but It's still not as significant as major news websites reported.
Good to read an opinion from a local!
Yes, there is much to do still ... usability and, above all, stability (lower volatility) are major issues. I am investigating ways to improve stability in cryptocurrencies, but it is not a trivial thing.
There are many things that can help improve stability: above all, a stable, long-term oriented reward system (where I see systems like Proof of Stake and Proof of Burn with an advantage over Bitcoin's PoW), and a stabie, not pump-and-dump-oriented community which really uses the currency, not only for trading.
