Wow...Comment found in Reddit about Cashaa:

"Is Cashaa software a revolutionary product ? NO. They promised Zero cost transactions but the same design make it not possible, their software it is a kind of local bitcoins online. If one person in India wants to send Money to UK they could buy bitcoin to a Indian trader, and then Bitcoin would be sent to UK were other trader would buy it giving money to the recipient of Cash. The reality is was that traders wanted to make money and the cost of transactions in Bitcoin became very expensive, so instead of Zero cost it could easily represent 5% or more of each transaction, apart you had to add the miner's bitcoin transaction cost. In fact their solution is quite inefficient. But even they can't implement their solution because Bitcoin trading is banned in India, now they blame regulator for delays...but in fact their solution wouldn't get any traction in market because is very costly do remittances with their system. Do your due diligence and keep away of Cashaa "
