I have bitcoins stored in an online Coinbase wallet. I've read this wallet should not be used for investing in an ICO as this will be Coinbase's wallet (not mine) and I won't have access to the private keys.
Is this true?
I looked into creating a multi-sig Coinbase vault as this seems like a good and safe middle ground. However, I noticed the vault has a 48 hour waiting period which is not desirable for buying into an ICO.
I'm running Mac OS X. Is Electrum wallet this best way to go about this?
What do people recommend?
