Just recently, I found this website called bitcoincloudservices and when I decide to purchase a few terrahash. It is asking me to pay 11.0000 ฿, which is 11.0 Thai Baht, according to the symbol. But when I received an email for the order receipt, they said I have to pay "Amount (BTC): 11.0." So, at this moment I am a bit confused on how much I have to pay, 11.0 ฿ Thai Baht (or 0.000894 BTC at the time of this post) or 11.0 BTC.
First of all and absolutely the most important thing is to not invest in whatever kind of mining. I am a old miner (myself and in cloud). Maybe you can earn but your investment is always in risk. Big risk. To leave the fact that most of cloud mining sites are scam. To leave a part the fact that the mining hardware is to expensive to have profit from it. But you must have in mind the difficulty in mining. The difficulty in mining is always an unknown factor which can overthrown everything within very few weeks (two or three). And is always unknown. No one can predict this factor. Having such weight in the expected revenues from the mining and having as the unique specific the impossibility to be known make the mining only an adventure and not an investment.
That for the mining and the cloud mining. As for your payment it would be better if you, before the bought of your terrahash, contacted the support of this site and ask about this problem. That sign is a sign which is used for bitcoin. And normally all the clod mining sites do the prices mainly in bitcoin (being bitcoin the currency which will be mined) but even in us dollar or euro. I don't know if that site you speak is a local one or international. If it is local and if your money have that sign maybe the owner of the site has "played" with this fact to have customers for its business. Knowing that the people will be cheated by the sign (believing that is the local money) and will buy. When they will understand the problem the money were paid.
