With the hard fork approaching I saw bitcoin.org suggests to shun away from the hard fork adopters such as coinbase, blockchain and xapo? Any good online wallet to use?
Does anyone know those which online wallet those big exchanges such as bitstamp, kraken, bitffinex use? Do they use 3rd party hot wallet or they are using their own proprietary online wallet?
Online wallets are unsafe because the your private key will be shared by the wallet provider. If you are looking to safe wallet you please go with the desktop wallets such as bitcoincore, electrum and multibit wallet to have bitcoins safely.
Polenix and bitrex are exchanges widely used and localbitcoins is my favorite whenever I need to convert the bitcoin for any fiat cash.
