Unfortunately, you may not contribute to ICO or Token Sale addresses by sending directly from your Rain account.
Smart contracts and ICO projects require you to participate with a private wallet that you control the private keys for. If you wish to contribute to an ICO, Token Sale, or any form of smart contract please first withdraw your BTC or ETH balance to a personal private wallet address and contribute from there.
If you contribute using your Rain account, Rain will not be able to recover the funds/tokens related to your contribution and may not be able to support the token in the future.
