On the contrary, bitcoin has been widely used for international payments and is way more efficient compared to traditional cross-border remittance. According to Mr. Smith, “They use Western Union, traditional banks; It is slow and it is expensive. And there are people that can stop you from sending that money, whether that’s good or bad. With bitcoin, I can send money. It’s fast. It’s cheap. And frankly, no one can stop me.“
The only apps that can do trades right now are the mobile apps for the various exchanges. And to view the market and coins available, the most popular site/app is Coin Market Cap. But there really isn't one that can handle everything for you. Which is why I'm currently building out an app called Matrix Portfolio, that will help you automatically pull in your trades from exchanges, so you don't have to manually enter them. As well as allow you to discover all the coins, and offer trading insights as well. Feel free to pre-register for the beta here: http://matrixportfolio.com
You’ll find that different exchanges cater to different markets. Today, most countries have at least one cryptocurrency exchange specializing in their own currency. There are exchanges that can accept New Zealand Dollars in exchange for bitcoin, for example. Other exchanges are known for certain pairs. Bithumb, for example, has particularly strong liquidity in the ETH/KRW (South Korean Won) pair at the moment (and it’s easily the most popular cryptocurrency exchange in Korea).
No, the successful trader is not me. I’ve gotten lucky a few times and I’m still refining and trying out strategies; on the other hand, I’m part of communities of people who trade on a daily basis to grow their portfolios, and while some of the results can be attributed to luck, a majority of it is based on fundamentals, good habits, and experience.
