I have joined a website in our country that offers buy and sell of bitcoins,the only one that offers our currency. When joining websites like this, what should be the right way in terms of getting or obtaining the bitcoin address?
Upon registration, you are given your on address by them. You can buy/sell bitcoin on their website. For me that sounds fair, nothing strange. But then, last week, I bought an amount of bitcoins from them and I can see it when I logged in to their website. But checking
https://blockchain.info/address/<my bitcoin address> shows no bitcoin balance.
I have checked a friend of mine's account which has transaction outside the website and can see it receiving bitcoins but the final balance is zero. But looking at their website, the balance is there. If I bought that bitcoin, why is it not in my wallet?
In addition, if you transfer to a bitcoin address outside their website, the fee is likely more than twice than using others like coinbase. I think this is for keeping you inside their website. Like for example I tried transferring 10 USD, and the fee is 15 USD. I have to cut out 25 USD on my address just for that. Crazy.
Are these things which I should be worried about?
