The year of 2017 was fantastic for the crypto markets, led by Bitcoin with 20x gains, while many altcoins gained even more: Of the major ones, Ethereum had outperformed, as it became the “coin of the ICOs.” Thanks to the Ethreum blockchain based ERC-20 token mechanism, projects could easily raise funds in ETH via their ERC-20 ICO smart contracts.
They are totally different though, we can't really compare what 2017 did bring to us. I mean, that time the market is fairly new, majority didn't even know what bull run is, that's why they just throw around money on ICO's.
We do identify some similarities between BNB of 2019 to ETH of 2017, whereas BNB is the coin used to participate in fundraising events taking place on Binance Launchpad. Following two successful fundraising events, Binance is looking forward to March Celer Network fundraising.
The thing with ICO's is that they're decentralize in nature (taken advantage o scammers), while the IEO (like Binance did) is totally not the same. So I wouldn't compare them at all.
Another similarity is the negative correlation to Bitcoin. During 2017, when BTC moved up, altcoins moved down and vice versa. Some altcoins, such as Ethereum, had the highest inverse correlation in comparison to Bitcoin. In 2018, mostly there was a positive correlation between Bitcoin and the altcoins. Over the recent month, we can definitely see such inverse correlation between BNB and BTC.
But when Bitcoin started to goes down in early 2018, ETH and XRP stared to increased and even reaches their all-time-high (ATH).
