It might have caused people to believe that anyone with any sort of slight incentive could start their own coin however bitcoin and ethereum have great benefits so I wouldn't attribute anything of their recent activity to bsv, btc was lower in price when bsv was released wasn't it too?
Everyone with bch got bsv so that definitely had an affect but bch and bsv are kinda scam coins anyway that have an overinflsted market cap (bch, to me, is a less secure version of ltc, without any other differences).
