The Light Wallet is a starter for those who are new to blockchain, but if you would like to invest more, we strongly suggest you register with a Ledger Nano.
The Light Wallet is an in-browser wallet, build from an open source library. It is really user-friendly, but it is also interoperable and can be used via Metamask, MyEtherWallet, Ledger Nano or any other web page using this library.
If you are an ICBM investor please create your account using the wallet with which you made your commitment. Otherwise continue to use Light Wallet, an in-browser wallet.
