In simple words.
Moving Average is a line which consists of dots, every dot is an average value of the price for the given period (for example for 50 days).
This way if you will compare current price to the current value of MA - you will know if the price is growing regarding the last given period (50 days) or falling.

Actually, all these instruments came from Stocks and Futures trading, not Forex
And yes, you could use any technical analyzes instruments on any price chart, on crypto as well. Still, you have to understand the mechanics behind the price movements and know what you are looking for.
For example, Support/Resistance levels work well to determine, where is a better price for entering the market and where it is time to exit.

World as it is now, divided by borders of different countries cant use single currency as single currency denies this borders.
It is not a coincidence that taxes are levied in the currency of the country, and the government strictly regulates the exchange of currencies.
Labor in different parts of the world is valued in different ways, a single currency carrying a unit value violates this, which is not beneficial for governments.
Dollar is already doing a similar job in third-world countries, where people prefer the jobs in the international companies as outsourcers, as the salaries tied to more valuable currencies (like programmers in Russia or Ukraine). I can only imagine, what could happen to the economy of some small country if companies start paying salary in bitcoins without the need to change it into national currency.

So, until globalization will not finish its dirty job and merge us all into one worldwide nation - single currency is not possible. Or at least not for everyone.

So in my opinion bitcoin as an international currency will be an underdog for a long time
Which also will make some people very rich.

Especially for small amounts, it is much easier to buy bitcoins on some local service (localbitcoins for example) and start trading with bitcoins already, because not all exchanges accept fiat currency.
Commissions and fees are often recalculated through bitcoins too.
So, It will be correct to start with bitcoins
Approximate minimal trade size for Bittrex is 0.0005 BTC and 0.0002 BTC for Poloniex. Other exchanges should have similar limitations.
So, it is pointless to start trading with lower investments:)
Furthermore, you will probably want to make more than one trade so that you will need a larger amount.
I would say, 0.05 BTC will give you a possibility to learn and experiment.

On today 0.05 BTC will cost you approx. 450 USD.

Greetings to BitcoinTalk Community.

I am working on “market maker” robot and want to ask about your experience and share mine.
MM (in my understanding) is a trading robot that should not rely on the long-term price direction and earn from the price irregularities or jumps, in other words - provide high-frequency scalping trades.
What I am using: Self-made bot for Poloniex and Bittrex (written in Erlang)

Strategy:
1.   Place buy-limit order at a price smaller than last ask price by 0.1%
2.   As soon as buy order executed, place sell-limit order at a price higher than buy price by 0.5% + both order’s commissions (or in other way: (buy cost + target percent) / (received size - commission percent) to take actual filled size into account)
The idea is to earn as frequently as possible, with fixed percent + commission taken into account.

Pairs: LTC/BTC, XRP/BTC, XLM/BTC (STR/BTC for Poloniex)
Results: Getting about 10-20 trades a day during volatile periods. The best results to this point showed XRP/BTC pair, seems to be more volatile.
10 – 20 trades a day, make 1% profit per day on average.

Problems:
0.1% target was too big for the LTC/BTC pair recently. The coin is just going down, and even order with such small target could hang for a couple of hours or even leave hanging while the price is going down.
Tried to lower the target, as low as 0.01%, still getting similar results.

Plans: Scanning orderbook.
Idea #1: Post orders only close to prices with relatively high volume
Idea #2: Analyze Buy and Sell order summary weight and post trades only when the average weighted price is higher than the last one.
 
So, what your opinion on this approach?
Maybe you know some good MM bots to take a look at?

I use both exchanges. Overall, my experience pretty similar, all crypto exchanges had troubles with support and withdrawals during intense periods. Nonetheless, as I remember, I had more difficulties with Poloniex. In 2017 it was almost impossible to approve your account on Poloniex, it took me like two months to get a response from the support.
 
Recap of latest news on each:

Bittrex recently changed the interface to more advanced and rolled out a beta version of new API. The registration on Bittrex was closed for a long time, and now they seem to be opening it again. It appears that they had problems with too big client base, and now they have expended their capacity. Based on the above, we can assume that Bitrex does not plan to go away:)

Payment provider  Circle has announced about acquiring Poloniex in February. Also, Poloniex signed an agreement with TradingVIew(great service for traders and analytics), and now you can connect your Poloniex account and trade through TradingView interface. So, they are developing as well.

Important, for me, differences:

Commissions:

• Bittrex has 0.25% commission regardless of maker or taker orders.
• Poloniex has 0.15% for maker and 0.25% taker fee.

Minimal trading volume:

• Bittrex - 0.0005 BTC (or equivalent in other coins).
• Poloniex - 0.0002 BTC (or equivalent in other coins).
