Everything is based on BTC. But who knows what it comes in future. Goverment doesn't like it, and pair are not gonna be only with btc, but with other coins. But I'm not sure if there will be added inseder transfer made with btc.
I think Btc still be the top
Actually, as far as I know not all altcoins relying on bitcoin. We all know bitcoin is the dominant crypto currency in the cyberworld which makes everyone interested due to its tremendous performance. In some point, not all altcoins relying bitcoin because it will still depends the demand of the society as well as in the bitcoin community. Bitcoin is so unpredictable that can survive all the dump situation and I believe it will still profitable and can give big help to each and everyone of us.
