The best Coin after BTC is ETHEREUM
It's evolution is the more interesting and it is ready to jump x3 or more within 4 to 7 weeks after the Hard Fork
BUT No need to replace BTC by ETH, the two are very good options (even if i personally prefere investing and holding in 4/5 ETH and 1/5 BTC)
I think there will be no problem with the SegWit and we won't even need this Fork. We don't have to worry at all !
Just have a seat and watch the market to make the best transactions we can ! Because it will bring tons of oportunity to make some cash, Let's Charts friends !!!
I agree with you
