ICO payment process working

[codycorn]

I been learning about ethereum and smart contracts. I have seen many ICO's are developing crowdsale smart contract based on Ethereum platform. But i figured out they are sill accepting BTC, Litecoin etc. Bitcoin and other coins will not be accepted by Ethereum crowdsale smart contract except Ether. So I been wondering

• How multiple coins are accepted in ICO's whose smart contract is based on Ethereum ?
• How exact number of tokens are sent to one who pay crypto coins and How this is done ?

I don't know if this questions is kinda silly or too technical. But i want to know its working.

Please point me to any documentation sources to learn about everything.

This depends on the developers, they can email you after subscribing or just set unique address for that specific token/coin that they want to accept.

• How exact number of tokens are sent to one who pay crypto coins and How this is done ?

There's already a fix price for the token and just do the calculation with that.

DEVs are only responsible people who can say the exact amount of bought tokens and this amount usually depends on contract lines. Maybe they will provide the different or unique address for receiving tokens but the final decision is made by devs.

The money to be accepted can be any valuable money. This is the decision of the project devs.
The tokens to be sent depends on the price of the token. And will be sent to the address you registered.
