Doesn't anyone remember that BTC market cap had lost one billion last month, and $1.5 billion last December? All cryptos are wild rides. BTC remains the strongest by far, but if the scalability issue isn't solved soon, I wouldn't be surprised to see it being passed by ETH.
This. BTC has had it's glory days already. BTC will never again rise to 10b mc anymore. It will slowly decline. BTC could never handle mass adoption because of scalability issues. ETH is currently the strongest candidate to overtake BTC but there might be others in the near future.
