Why is it dangerous to keep all your cryptocurrencies in coinbase? What will happen if you keep your cryptocurrency in coinbase? Also, after you sell your fraction of a bitcoin can you withdraw that money or invest it back into bitcoin? When the price of bitcoin drops, will it cost less than before to buy a bitcoin? Am I too late into bitcoin? What is the best digital wallet and is “coinbase vault” on your recommendations?
It’s dangerous to keep your bitcoins in any wallet to which you don’t control the private keys. This goes for online wallets, exchange wallets, gambling or game site wallets and even personal wallets on your own machine if you haven’t made a backup of their private keys. Major exchanges have been hacked or otherwise been taken down before – see Mt. Gox as the best known example – and people who had their coins on such exchanges have been very fortunate to get even a fraction of their coins back.
