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?
Don't use a web wallet, period. Sure you can find some that actually allow you to hold your own private keys but usually, what you'll find is that either there is a difficulty in exporting the private keys when you need it since they don't support one fork or another or that they just don't give you access to it at all.
Use electrum, it's a small download and it's fast and safe.
Unless you can't download software for whatever reason, then use wallets on bitcoin.org that are listed as you being in full control.
Yap, electrum is your best choice, lightweight user friend and very fast. You can also adjust fees in case you need it. Well web wallets has its used though, but if you planning to hold big amounts then its not recommendable. And its really hard to trust them specially your private keys.
I have used them in the past but just for small amounts and for trading purposes only. I would immediately moved my coins to my electrum wallet so that I can have a good night sleep knowing that my coins is safe with me.
