im currently watching a youtube interview on segwit for bitcoin and i just wanted to say a few things
first make sure you're bitcoin is not on an exchange. even though keeping your coins on an exchange is so stupid to begin with since it can be gone in a moment
second your wallet should support bit 148 so on august first when the soft fork happens you have assurance.
third once segregated witness(segwit) is activated the price will most likely crash temporarily just like lightcoin did because buy the rumor sell the news philosophy
also as an alternative if you are scared about this whole drama as i would call it. you can always put most or all of your bitcoin in another well established crypto currency like lightcoin or dash because in my mind(just speculation) dash and or lightcoin will probably rise because of people who are getting out once the possible scary dump of btc.
just be ready for august first and ask your wallet dev questions if you are still worried
im new to this whole soft fork as well and am still wrapping my head around it.
