1 ETH : As the smart contract is made on this platform, preference to the ETH is given all the time. It becomes far easy to track back the funds sent to the ethereum smart contract and thus makes it far easier.

2 BTC : Many people dont like idea of converting their BTC to ETH and then sending it for token purchase. So this has become the second most vest currency to trade the ICO tokens.

3 BCH : Not much popular until the year 2018 has arrived when people has started taking more interest in this coin and thus they love to buy with this one too.

4 Rest follows if the coins are being prepared on the hubs like WAVES.
