What I really miss is the acceptance by politics. Politicians should really start to look into the whole crypto world.
They should start to understand how the cryptocurrencies could be used in everyday life. At least in Germany, I don't see any politician talking about Bitcoins oder Altcoins because they just ignore it.
It's seen as a trend that will disappear soon, but that's not the case. Cryptocurrencies are here to stay and will be developped further.
There are very solid reasons that governments are not accepting cryptos as currencies. Crypto are decentralized which means the transactions are private and anonymous. This makes it difficult for governing party to take actions against illegal activities and scams that might occur using these digital coins.
Government are developing and regulating them but are considering them just as an asset rather than currency which seems a pretty fair decision to me. If crypto assets are legalised and made a currency, the country will go under chaos, accumulation of black money and people will not pay their taxes.
