What happened in China with that big community didn't affect the bitcoin. How do you expect Argentina cause the bitcoin to be crashed? It will never happen.
Well, there was at least one flash crash (5000 -> 3000) where many people made China's "ICO ban" responsible for.
And they seem to be targeting explicitly cryptocurrency holders, it seems. It doesn't apply to gold or other assets, just cryptocurrencies.
No, it's a "capital gains" tax, not a cryptocurrency tax (I maybe was a bit imprecise in the OP), so holders of other assets are also affected.
It's lastest president Cristina Fernandez left the Argentina in poverty, so now Mauricio Macri (It's current president) made this new law because many people is making profits over BTC in there.
That's what Mr. Macri wants you to think, yeah (Argentina wasn't left "in poverty", but there was much corruption and lots of bad decision making in the Kirchnerist government. But don't be naive, Macri is from the same breed.)
i'd be curious to know how much liquidity and trading volume argentines represent. i've been hearing about significant adoption there for years, so it's possible that such sell pressure could spill over into the global markets.
There is only one exchange, Ripio, and it doesn't have high volumes; there are also three or four fixed-rate shops and pretty much LocalBitcoins movement. But most Argentine Bitcoin whales got Bitcoin via mining (electricity was extremely cheap until 2015/16) and are holding them to cash out in US dollars or other currencies, so the ARS/BTC movement is probably a tiny fraction of the whole "Argentine volume".
But there are
few full nodes (only 20) tracked by Bitnodes.
however, 15% per year is not unreasonable for capital gains taxes.
Yes, I also think it's not unreasonably high.
