I registered on Bitstamp.net end deposited 130 $. The problem is when I'm filling the gap (simple order) and writing 130 $ it shows appr. 0.1 bitcoins. As the rate exchange is about 30 $ for 1 BTC it should give about 4 Bitcoins. I don't know what the matter is. Anyone can help me?
I'm not sure what you are saying, but BitSTAMP is a market exchange. Without knowing your knowledge of how market exchanges work, forgive me if you are already aware of this.
To buy 4 BTC immediately on a market exchange you need to enter the order (bid) with a price not necessarily at the lowest ask price but at a price high enough that all 4 BTC you want to buy are listed at.
For instance, if the order book (ASK) looks like:
QTY AMOUNT
0.5 $31.00
1.0 $31.50
2.0 $32.00
2.0 $33.00
2.0 $34.00
then to get 4.0 BTC immediately you need to enter the order as 4.0 BTC with a price (bid) of at least $33.00.
If you were to place an order for 4.0 BTC at a lesser amount, like $31, the order would only get "filled" with 0.5 BTC -- as only 0.5 BTC are available for sale at that price. If you leave the partially filled order there, eventually it might get filled if other sellers place sell orders at that level.
