bitcoins is of the most active crypto currency of the world and it will remain for ever.
well it is definitely not the most active, it is the most popular but there are cryptos that are more active such as ethereum
Ethereum is dead, go for Moonero. I spelled it wrong because I believe it will go higher and higher, as it is going to be used against bitcoins in dark markets. Just can't wait to buy some stuff if this goes on air.
