It seems to me that the very formulation of the question of which purse after the first of August can store two types of bitcoins is premature. Perhaps there will be no separation and all worries will be in vain. In addition, it is unlikely that anyone now calls such a purse.
Don't listen to this guy. He's speaking nonsense and only made this post to get paid. If one were to wait until after a potential split to select which wallet to protect their bitcoin in the event of a split, they'd be...too late!
If there will be chain-split, I want to keep my BTC right now in wallet whitch will be able to access two kinds of BTC after 1st Aug & ofcourse, whitch is safe.
Is there anyone with information about it? ( except personal hard disk wallet.. that's too difficult for me )
There's a lot of people with information about it. The frustrating part of your question is that you clearly didn't try to look for the answers you seek before posting a new thread. If you spent 5 minutes looking around this forum you'd find a thread or 5 talking about this exact same issue!
First, you need to know what you're protecting against. Anyone with control of bitcoin will have the opportunity to select which version of bitcoin coin they want to use in the event of a split. The tricky part is having control of bitcoin. If you don't have possession of the private keys of your wallet you don't actually control bitcoin. Generally speaking, keep your bitcoin off of the online exchanges/online wallets unless they give you access to your private keys or have stated that they'll guarantee you'll have the choice of which coin to proceed with post-split.
