To the point of economics/markets/trading, look at the practical use-case of Bitcoin; a global store of value asset that may be transmitted via a communications channel.
To illustrate how global, I asked which country people were from in this small forum, of those who spoke out, in two days the following tally;
9 responded from Phillippines
5 responded from Indonesia
3 responded from India
2 responded from USA
1 from Ukraine
1 from Bangladesh
1 from East Timor
the above was a count of posters from here:
https://bitcointalk.org/index.php?topic=1853019.0Its awesome to see how bitcoin has gained a worldwide presence & is increasingly becoming a currency of the people.
Some say the golden days of crypto are far gone, but those results make me excited for cryptos future.
I don't think crypto is truly mainstream yet & don't know if it ever will be, but these results are exciting.
