Actually, BTC is not the first digital currency, but it is the fisrt successful Crypto. Even though Ethereum is considered second best, there are many coins in the space competing and claiming to be better than BTC, so is ethereum now have many coins on its toes claiming to be better than what Ethereum have to offer.

For this year, there are many good projects coming up on Ethereum platform. That's why it is gaining more space in the crypto world. Interesting times coming up.
