When we talk on August 1, 2017, it promises to be a highlight in the future of Bitcoin, as there is a great chance of a division in the blockchain by UASF of the improvement BIP 148 (the Soft Fork that we already talked about in another post). Note that if most miners (mostly those with the greatest hash force) do not adhere to and support the activation of SegWit through BIP148, Bitcoin's blockchain will be split in two. Thus creating two types of Bitcoin tokens, one for coins in the bifurcated chain and another for the Bitcoin legacy of coins in the chain that did not execute the BIP148.
Many speculate and come to consider good news, that every bitcoin existing in the instant prior to UASF would be effectively copied to both strings. Where would you have your Bitcoins in both networks the new one with BIP 148 and Legada currently, one with SegWit and another without. But as you reader, you must already be concluding, this will be a mess and will bring a lot of risk to the market.
First, be aware that a division of the chain is a high-risk situation. There are real chances of disturbances in the order including some drastic changes in Bitcoin's change. Make sure that you are not holding more value in bitcoin than what you are willing to lose.
