If there is a hardfork on august 1st what will happen to my transaction of 0.00006BTC with a fee of 1bit? I have BTCitcoins on that wallet, is dangerous have a pending transaction during the split of the currency? Thanks.
If there is a fork and you have an unconfirmed transaction created and sent before the fork, your transaction will likely be able to be confirmed on all chains following the fork. This means that you will have coins on all forks. However you should not trust the confirmations that you see for your transaction until it has several tens of confirmations. This is because the chain that you are looking at could, at any time, be potentially wiped out and replaced by a different chain. If that other chain does not have your transaction confirmed in it, then your transaction will become unconfirmed again.
Also, it is important to note that August 1st is not the only time that a fork can occur. With false signalling and spy mining, BIP 91 (which just locked in) could cause forks once it activates.
